Why Don’t British People Use Umbrellas?

For Hong Kong immigrants living in the UK, the sight can be quietly baffling: the sky is grey, a light rain is falling, and yet the British people around them walk on without a care, heads bare, not even bothering with a hood. In Hong Kong, reaching for an umbrella at the first sign of rain is pure instinct. In Britain, people seem almost immune to it. This is not simply a difference in personal habit — there is a coherent logic behind it, shaped by climate, infrastructure, history, and culture.

The rain itself is fundamentally different. Hong Kong rain arrives fast and falls hard. Within minutes, streets can flood and anyone caught without an umbrella is soaked through. British rain is something else entirely. Most of the time it is a drizzle — so fine it feels closer to mist than rain, drifting rather than falling, slow to penetrate fabric. There is even a cultural phrase for it: “It’s only drizzle.” That dismissiveness is telling. For the British, this kind of rain simply does not register as a problem worth solving.

Wind, however, is the more important factor. Britain sits on the edge of the Atlantic, exposed to the prevailing westerlies year-round. Winds are unpredictable and gusts are common. In these conditions, an umbrella becomes less a tool of protection and more a liability. Open one and it may invert within seconds, or the frame may snap entirely. The bins along London streets tell the story — bent and broken umbrellas are a regular sight, casualties of a single gust. Many British people have simply concluded that fighting the wind with an umbrella is more undignified than getting a little wet.

The practical alternative is the waterproof jacket. A good one repels both wind and rain, leaves both hands free, takes up no space on the Tube, and will not be destroyed by a sudden squall. It is the rational solution to the specific conditions Britain presents, and it explains why outdoor and hiking brands do such brisk business in a country with no mountains nearby.

How people travel also shapes how much the rain matters. In rural and suburban Britain, the car is dominant. Many journeys involve nothing more exposed than a short walk from a front door to a car, and from a car park to an entrance. The cumulative time spent outdoors in the rain can be remarkably small. Hong Kong operates on an entirely different model. The city runs on public transport, and getting around means walking — to bus stops, MTR stations, through covered walkways that nonetheless have gaps. Exposure to the elements is unavoidable, and an umbrella is as essential as a phone.

Hong Kong’s relationship with rain also carries a historical weight that has no equivalent in Britain. In the 1990s, Hong Kong suffered from significant acid rain, driven by industrial emissions from across the border. Rainwater became genuinely harmful — corrosive to skin and damaging to clothing. That era conditioned an entire generation to treat rain as something to be blocked rather than tolerated. The acid rain problem has eased since, but the habit of caution it produced has not.

The city’s physical form adds another dimension. Hong Kong is dense with high-rise buildings, and when rain falls across that kind of vertical landscape, it does not stay clean for long. Water picks up grime as it runs down facades and bounces off ledges and canopies before reaching street level. The rain that hits a pedestrian in Mong Kok has travelled a long way and touched a lot of surfaces. In that context, an umbrella is not just about staying dry — it is about staying clean.

Cultural attitude completes the picture on the British side. Generations of living with persistent, unremarkable rain have produced a studied indifference to bad weather. The British talk about weather constantly — not because they find it dramatic, but because it is so relentlessly present that it has become the default small talk, a social ritual rather than a genuine complaint. Getting caught in a bit of drizzle is not seen as a hardship. It is simply Tuesday.

For Hong Kong people settling in Britain, this difference can take time to internalise. The umbrella habit was not arbitrary — it was built by monsoon rains, acid rain, high-rise grime, and a transit-dependent city that puts people outdoors in all conditions. In Britain, the rain is lighter, the wind is stronger, the car is closer, and the cultural bar for what counts as bad weather is set considerably higher. Both responses are logical. The conditions that produced them are just very different.

Why Is There Only One Global Oil Price? Why Americans Still Pay More and Why North Sea Drilling Won’t Change It

Leave a Comment / Explainers / 胡思

When the news talks about oil prices, it almost always refers to Brent crude. Many people find this puzzling. Oil is produced in different countries, with different qualities and transport distances. In theory there should be many different prices. Yet in reality the world behaves as if there is almost a single global oil price.

The reason is simple. Oil markets are global.

Brent crude comes from oil fields in the North Sea between Britain and Norway. Originally it was simply one regional type of oil. Over time, however, it became the benchmark for global oil pricing as futures trading developed. Today many crude oil contracts around the world are priced relative to Brent, with small adjustments for quality or transport.

For example, higher quality crude might sell one or two dollars above the Brent price, while heavier crude might trade at a discount. Regardless of where the oil is produced, prices tend to move around the Brent benchmark. Brent futures trading creates a transparent price signal used by energy companies, airlines and commodity traders around the world.

One reason oil forms a global price is that transport costs are relatively low. A large oil tanker can carry around two million barrels of crude. Shipping oil across oceans typically costs only a few dollars per barrel. Compared with today’s oil price of roughly $100 per barrel, that cost is small.

Whenever price differences appear between regions, traders move quickly. If oil becomes cheaper in one market, traders buy it there and ship it to a higher-priced market. Demand rises in the cheaper region and prices increase. Supply rises in the expensive region and prices fall. This constant arbitrage prevents large price differences from lasting.

That is why even different types of crude oil tend to move together. West Texas Intermediate, for example, often trades close to Brent. Brent simply appears in the news more often because it is the most widely used benchmark.

Oil is usually sold at export terminals near where it is produced. Buyers may be refineries or large commodity trading houses. Once loaded onto tankers, the oil travels across the world. Sometimes a cargo is bought and resold several times while still at sea before its final destination is decided. This active trading network keeps the global market tightly connected.

This also explains why Americans still feel the impact of rising oil prices. The United States is now the world’s largest oil producer, pumping more than 13 million barrels per day. But global supply is around 100 million barrels per day. American oil can be exported, and domestic refineries must compete with global buyers. When international oil prices rise, petrol prices in the United States rise as well.

The same logic applies to Britain. Some argue that expanding North Sea drilling could reduce energy costs. Yet oil produced in the UK sector of the North Sea accounts for less than 1% of global supply. Even if new fields are developed, additional output would likely amount to only tens of thousands of barrels per day. Compared with a global market of roughly 100 million barrels daily, the effect on price would be negligible.

Others suggest a more direct approach: requiring all oil produced in British waters to be used domestically instead of exported. At first glance this might appear to lower local fuel prices. In practice the drawbacks would be significant. Oil companies currently sell at international prices. Forcing them to sell domestically at lower prices would reduce investment returns and weaken incentives to explore and develop new fields. Britain’s refining system is also integrated with global supply chains. Different refineries require different crude types, and the country still imports some oil and petroleum products. Restricting exports would disrupt these supply chains while sacrificing international revenue, yet prices would still be influenced by the global market.

In other words, oil markets are no longer national markets but truly global ones. Prices are determined by worldwide supply and demand rather than by any single country. Brent crude appears in the headlines precisely because it represents the closest thing the world has to a common oil price.

From Work Ban to Hotel Requisition: Britain’s Self-Fulfilling Asylum Policy Trap

Leave a Comment / Explainers / 胡思

The central contradiction of Britain’s asylum system today can be summarised simply: the more restrictive the policy becomes, the harder the problem is to manage.

The story begins in 2002. Under political pressure, the government of Tony Blair removed the right of asylum seekers to work while their claims were pending. Previously, if an application had not been decided within six months, asylum seekers could enter the labour market. After the change, they were effectively required to rely on government accommodation and a small weekly allowance.

The intention was political damage control. The government wanted to avoid accusations that the system was attracting migrants or allowing them to “take British jobs”. Yet the long-term consequences were very different. Once asylum seekers were banned from working, they became dependent on the state throughout the entire decision process. Whenever decisions slowed, the demand for accommodation inevitably increased.

In the early years the system still functioned. Asylum seekers were placed in what was known as the “dispersal accommodation” system. This meant that government contractors rented ordinary housing across different towns and cities and distributed asylum seekers across communities instead of concentrating them in large refugee camps. But as global conflicts increased, applications rose and decisions slowed, the system’s weaknesses began to appear. When dispersal housing ran out, the government had to turn to temporary solutions. Hotels gradually became the default form of accommodation.

Restrictive policies also produced another side effect. When asylum seekers are banned from working and housed by the government for long periods, it becomes easy for the public to perceive them as a burden. This design itself fuels resentment and hostility. As public anger grows, politicians respond with even tougher policies. A cycle emerges: the stricter the rules, the greater the hostility; the greater the hostility, the stricter the rules become.

Brexit took place in this political climate. After leaving the European Union, the United Kingdom also withdrew from the Dublin Regulation. Under this system, asylum claims were generally the responsibility of the first European country a migrant entered. That allowed Britain to transfer some applicants back to mainland Europe. The system also relied on a shared fingerprint database that allowed countries to check whether someone had already applied for asylum elsewhere. After Brexit, the UK lost these mechanisms. It became harder both to return migrants to EU countries and to verify their previous asylum claims.

Another change followed. Today the small-boat crossings of the English Channel dominate political debate, but before Brexit this route was almost non-existent. When Britain still participated in European asylum cooperation, some migrants could be returned to other EU states. Once those mechanisms disappeared, Channel crossings gradually increased and quickly became a powerful political symbol.

Pressure on the system worsened further in recent years. Toward the end of its time in office, the Conservative government deliberately slowed asylum processing in the belief that long delays would reduce the system’s “pull factor”. The theory was that if asylum seekers expected a difficult and prolonged process, fewer would attempt to come to Britain. In practice the opposite occurred. Applications piled up, waiting times lengthened and accommodation demand expanded rapidly. A policy intended to deter migration ended up making the system far more expensive and harder to manage.

In this environment the Conservative government introduced another deterrence policy: the Rwanda scheme. Its central idea was to transfer some asylum seekers to Rwanda for their claims to be processed there. The hope was that this would discourage migrants from attempting the journey to Britain. The government paid hundreds of millions of pounds to Rwanda, yet the scheme was designed to process only a few hundred people — insignificant compared with the tens of thousands of asylum applications each year. Rwanda is also an authoritarian state. Outsourcing asylum responsibilities to such a regime carries obvious moral risks and practical dangers. Once such an arrangement begins, the host country could easily gain leverage over Britain. If the regime were to face political instability or eventual collapse — a common fate of authoritarian systems — the question of what would happen to those transferred there would become even more complicated. Ultimately the policy ran into major legal and political obstacles and never truly took effect.

The current Labour government has now introduced another measure: offering cash payments to some rejected asylum seekers to encourage voluntary departure. The logic is financial. Paying a lump sum may be cheaper than housing people for years. Yet in an already polarised political climate, such policies are easily framed as paying migrants with taxpayers’ money, which may only deepen public hostility.

Meanwhile, most European countries have moved in a different direction. Many allow asylum seekers to work after three to six months, enabling at least some of them to support themselves. Accommodation systems are also structured differently, with purpose-built reception centres rather than emergency hotel use. The European Union has gradually harmonised these policies, including reducing the maximum waiting time for labour market access to six months.

Looking back over this policy trajectory reveals a common pattern. Governments of different parties have repeatedly responded to anti-immigration pressure with stricter policies. Each step appeared politically safer in the short term. Yet over time these decisions pushed the system toward the most expensive and least efficient outcomes.

The work ban prevented self-sufficiency. Brexit weakened international cooperation. Slower processing created enormous backlogs. The Rwanda scheme consumed public funds without solving the problem. These policies may appear unrelated, but they follow the same political logic. When a system is designed primarily around deterrence, it can end up reinforcing the very problem it seeks to control. The result is a self-fulfilling policy trap.

Restoring order to the system may not require complicated innovations. Many European countries recognise a basic reality: asylum seekers waiting for decisions need the opportunity to work, and cross-border cooperation is essential for managing migration. If Britain wishes to escape its current predicament, the answer may not lie in ever tougher policies but in learning from the approaches already used across Europe. In the long run, rebuilding institutional cooperation with Europe may be the most straightforward path back to a functioning system.

One Formula, Billions in Funding: How the UK Allocates Money to Scotland, Wales and Northern Ireland

Leave a Comment / Explainers / 胡思

The UK spends hundreds of billions of pounds on public services every year. Yet when it comes to Scotland, Wales and Northern Ireland, many people struggle to explain how the money is actually allocated. It is often assumed that there must be a sophisticated formula calculating what each nation should receive. In reality, the mechanism used to adjust these allocations is surprisingly simple. It is known as the Barnett formula.

The Barnett formula was introduced in 1978 and is named after Joel Barnett, who was then Chief Secretary to the Treasury. Its origin was pragmatic rather than constitutional. When spending on public services in England increased or decreased, the government needed a quick way to adjust the budgets of Scotland, Wales and Northern Ireland at the same time. The Barnett formula was designed to solve that problem. It deals with how much spending should rise or fall, not with how total resources should be distributed.

The calculation itself is straightforward. When the UK government increases spending on a service in England that is devolved elsewhere, such as health or education, the other three nations receive a proportionate increase based largely on population. If spending on a service in England rises by £10 billion, Scotland, Wales and Northern Ireland receive additional funding according to their population shares. Because the adjustment happens automatically, the Barnett formula is often described as an automatic mechanism for increasing or decreasing funding.

The crucial point is that the formula only applies to changes in spending, not to the overall level of funding. Each devolved administration already has a baseline budget, and that baseline was not determined by the formula. It emerged gradually from historical spending decisions and political negotiations. If one nation started with higher spending per person, the formula does not correct that difference. It simply increases or decreases funding on top of the existing base.

One of the most prominent recent controversies illustrates how this works in practice. The high speed rail project HS2 is being built entirely within England. Yet the UK government classified it as an England and Wales project. One argument originally put forward was that HS2 could allow trains from North Wales to reach London more quickly through connections to the new network.

Rail infrastructure in Wales is not fully devolved. Because of this classification, HS2 spending does not trigger additional Barnett funding for the Welsh government. Politicians in Wales have therefore argued that a railway built entirely in England is being treated as a project benefiting Wales, and that Wales is losing funding it would otherwise have received.

The argument became more contentious after later changes to the project. Parts of Phase 2 were cancelled, including the section that would have connected Birmingham to Manchester. As those plans were abandoned, the earlier claim that the project would significantly improve rail journeys for North Wales became harder to sustain.

The dispute highlights an important limitation of the Barnett formula. The formula only operates when spending is classified as applying to England alone. If the UK government categorises a programme as covering England and Wales together, additional funding for Wales may not be triggered even if the spending itself takes place almost entirely in England. In many cases, the political argument is therefore not about the calculation itself, but about how spending is classified.

The contrast with Germany makes the difference clearer. Germany is a federal state with a formal system of fiscal equalisation between its regions. The system calculates the fiscal capacity of each state. Wealthier states transfer resources to poorer ones, and the federal government also provides additional support. The objective is explicit. Public services across Germany should not diverge too widely simply because some regions are richer than others.

The UK system works very differently. The Barnett formula does not measure fiscal capacity and it does not aim to equalise spending levels. It simply distributes changes in spending on top of existing budgets. As a result, public spending per person in Scotland has long been higher than in England, with Wales and Northern Ireland also typically receiving more per capita. The formula itself does not attempt to remove those differences.

Another striking feature is that the Barnett formula was never intended to become a permanent system. It was introduced as a temporary administrative arrangement. Yet it has remained in place for decades. As devolution developed and the powers of Scotland, Wales and Northern Ireland expanded, this simple mechanism gradually became a central part of how funding is allocated within the United Kingdom.

On the surface the Barnett formula looks like a neat calculation. In practice it reflects a political compromise embedded in the UK’s constitutional structure. Compared with the carefully designed fiscal equalisation systems found in federal countries such as Germany, the UK approach is remarkably simple. Public spending is not determined by a comprehensive formula calculating fairness. Instead, it evolves gradually on top of historical spending patterns.

Understanding the Barnett formula therefore reveals something broader about the UK state. Many of its most important institutions were not created through grand design. They emerged incrementally and persisted because they were convenient. The allocation of public spending across the UK’s nations is no exception.

British Columbia Ends Winter Time: Will Other Canadian Provinces and U.S. States Follow? What Is Europe Waiting For?

Leave a Comment / Explainers / 胡思

On 8 March 2026, British Columbia will move its clocks forward for the final time, becoming the first Canadian province to abolish winter time. The decision does not bind the rest of Canada, but it breaks a long pattern of hesitation.

Under current rules, North America begins daylight saving time on 8 March 2026 and returns to standard time on 1 November. Europe will switch on 29 March and revert on 25 October. Australia and New Zealand will end daylight saving time on 5 April 2026 and resume it on 27 September. In other words, most jurisdictions that observe seasonal clock changes will continue as usual in 2026. British Columbia stands apart.

In Europe, the European Parliament voted in 2019 to end the twice-yearly clock changes and allow member states to choose either permanent standard time or permanent daylight saving time. The reform was originally scheduled for 2021. It stalled because governments could not agree on which option to adopt, and because the pandemic and subsequent energy crisis displaced the issue. The Parliament’s position remains on record, but the Council has yet to forge consensus. The obstacle is no longer principle, but coordination.

British Columbia’s case rests on familiar arguments. Research links clock changes to sleep disruption, short-term rises in traffic accidents and cardiovascular stress. Businesses must adjust systems and schedules twice a year. A fixed time is presented as a modest but tangible gain in stability. Yet time policy is not only about health. It is also about integration.

British Columbia shares the Pacific time zone with Washington State. Vancouver and Seattle are closely connected economically. In several border towns, neighbourhoods function as a single community across the line. Schools, shops and services intertwine. If a sudden one-hour gap emerges each winter, daily routines could be thrown off. Commuters, shift workers and families who cross the border regularly would have to recalibrate their lives. The difference is small in theory, but it may be disruptive in practice.

For years, provinces and states have waited on one another. Ontario has passed legislation supporting permanent daylight saving time, conditional on neighbouring U.S. states doing the same. More than 19 U.S. states have approved similar measures, pending action by Congress. Each side has been waiting for the other. With British Columbia now moving first, the question is whether it becomes a catalyst for broader reform in North America, or remains an isolated case.

Daylight saving time was once justified as an energy measure. The world it was designed for has changed. Digital markets operate across time zones. Supply chains span borders. British Columbia has chosen to act rather than wait. Whether others follow will reveal how willing governments are to bear the cost of leading, instead of postponing yet again.

How Sunbelt Regions Are Reshaping the Global Economy

Leave a Comment / Explainers / 胡思

The energy transition is not merely a matter of emissions reduction; it is also about costs.

In the era of renewable energy, low latitudes become competitive. The so-called Sunbelt encompasses Southern Europe, North Africa, the Middle East, India, Australia, the southern United States, and large areas of sub-Saharan Africa. These regions receive between 2,500 and 3,500 hours of sunlight annually, while many parts of Northern Europe receive only about 1,000 hours. Although the price of solar panels is similar globally, the output can differ significantly, sometimes by a factor of two.

The key to solar energy lies in capacity factors. The same equipment in India or North Africa generates far more output than in the UK or Germany. Over the past decade, the cost of photovoltaics has fallen by more than 80%. As equipment becomes cheaper, geographical advantages become apparent. If electricity prices can be kept between €20 and €30 per megawatt-hour in the long term, energy-intensive industries will naturally relocate. Sectors such as aluminum, steel, hydrogen, and data centers will not cling to high electricity prices.

A turning point emerges here.

In the era of fossil fuels, resources were concentrated in a few exporting countries. Solar energy, however, is widely distributed and tends to favor low latitudes. Many developing economies, previously constrained by energy shortages, now have the opportunity to turn the tide. India already has a manufacturing base and a large market. If coupled with stable and inexpensive green electricity, its attractiveness will increase further. Sub-Saharan Africa has long struggled with power shortages, but if photovoltaics and energy storage are deployed effectively, the threshold for industrialization will lower.

The global factory may not always be in East Asia.

Low electricity prices are the most compelling incentive. Capital will take notice. As energy costs comprise a higher proportion of total costs, geographical advantages become more pronounced. If Sunbelt countries can ensure the stability of their electricity supply and transparency in their systems, they could very well attract a new wave of industrial migration.

As for Europe, the issue is more straightforward. Rather than forcing photovoltaics in areas with insufficient sunlight, it would be better to first unlock the potential of Southern Europe. There remains significant solar capacity in Spain, Portugal, Southern Italy, and Greece. Strengthening cross-border electricity grids to transmit excess power from the south to Central and Northern Europe is a pragmatic choice. Although the cost of high-voltage direct current transmission is not low, transmission losses are manageable, making it a one-time infrastructure investment.

As demand continues to rise, collaboration with North Africa can be considered based on circumstances. The Mediterranean is not far away. While political risks exist, energy diversification itself is a method of hedging against risks.

Energy has never been purely a technical issue; it is a combination of geography and systems.

The sun will not move, but industries will.

In the past, those who controlled oil wells held the advantage. In the future, those who harness sunlight will gain the upper hand. The question is not whether the sun is fair, but whether countries understand how to move towards it.

The Astronomical Logic of the Lunar Calendar

Leave a Comment / Explainers / 胡思

The lunar calendar is not a vague folk tradition but a system governed by clear astronomical rules. Its central question is singular: how to simultaneously track the moon and the sun, ensuring that months follow lunar phases while years remain aligned with the four seasons.

The historical evolution can be summarized. The ancient ‘Xia Calendar’ established the prototype of a system that began the year in the month of Yin. In 104 BC, the Western Han dynasty promulgated the ‘Taichu Calendar’, which first fully established a lunisolar calendar system that set the new moon as the start of the month and corrected the solar year with solar terms. In 1645, during the early Qing dynasty, the ‘Shixian Calendar’ was implemented, introducing Western astronomical calculation methods to derive new moons and solar terms based on actual celestial phenomena. Since then, the calendar has entered a phase based on precise astronomical calculations. The modern lunar calendar has developed along this technical trajectory.

The specific calculation methods are regulated by the ‘Compilation and Issuance of the Lunar Calendar’ (GB/T 33661-2017), implemented in mainland China in 2017. The principles are not mysterious and can be summarized in four steps.

First, the month is determined by the astronomical new moon. When the moon and the sun have the same ecliptic longitude and the moon’s surface is not visible from Earth, this moment is called the new moon. According to Beijing time, the day of the new moon is designated as the first day of the month. A synodic month averages approximately 29.53 days, so lunar months alternate between 29 and 30 days without a fixed pattern.

Second, the year is determined by solar terms. The Earth’s orbit around the sun creates 24 solar terms, with one term occurring every 15 degrees. Among these, 12 are ‘mid-terms’, such as the spring equinox, summer solstice, autumn equinox, and winter solstice. Mid-terms are crucial for correcting the calendar year.

Third, a month without a mid-term is designated as a leap month. Twelve synodic months total about 354 days, which is roughly 11 days shorter than the tropical year of about 365.2422 days. To prevent solar terms from advancing each year, the rule states that if there is no mid-term between one new moon and the next, that month is designated as a leap month, retaining the name of the previous month. On average, there are about 19 leap months in 7 cycles, but the actual determination depends on the celestial phenomena of that year.

Fourth, the eleventh month is determined by the winter solstice. The standard requires that the winter solstice must fall within the eleventh month of the lunar calendar. By calculating forwards and backwards from this point, it ensures that the first day of the lunar new year generally falls between late January and mid-February in the Gregorian calendar, maintaining the relative stability between the Spring Festival and the beginning of spring.

The logic of this entire system is clear: the new moon addresses the ‘month’ issue, mid-terms address the ‘year’ issue, leap months resolve the discrepancies between the lunar and solar cycles, and the winter solstice establishes the sequence of the year. The tools for calculation may have evolved from counting rods to computers, but the principles remain unchanged.

Thus, the lunar calendar is neither purely lunar nor purely solar; it is a lunisolar calendar based on astronomical observations. Its stability lies not in tradition but in rules.

Time originates from celestial bodies, and calendars merely translate celestial phenomena into human order. What appears complex is, in fact, the repeated application of a few clear principles.

The Astronomical Mystery of Lunar New Year and Missing Day 30

Leave a Comment / Explainers / 胡思

On the eve of the Lunar New Year in 2026, many people noticed an unusual occurrence: there is no Day 30 this year. The twelfth month of the lunar calendar has only 29 days, and after Day 29, it directly transitions to Day 1 of the new year. This is not a calendrical error or a deliberate adjustment, but rather a natural consequence of astronomical movements. In fact, from 2025 to 2029, there will be five consecutive lunar years without a Day 30, with the next occurrence not expected until 2030.

To understand this phenomenon, one must first grasp the fundamentals of the lunar calendar. The lunar calendar is a lunisolar calendar. Months are determined by the waxing and waning of the moon, with each astronomical new moon, or ‘Shuo’, marking the first day of the lunar month. The average duration from one new moon to the next is approximately 29.53 days, known as a synodic month. Since calendar dates cannot be fractional, each month can only have either 29 or 30 days. If the interval between two new moons is less than 30 days, that month is a short month with 29 days; if it exceeds, it is a long month with 30 days.

When the twelfth month of the lunar calendar happens to be a short month, the last day of the year is Day 29, not Day 30. This entirely depends on the actual length of the synodic month. The year 2026 falls into this category, hence the absence of Day 30. Such arrangements are not uncommon; they are a natural result of the moon’s orbital cycle.

As for why the Lunar New Year does not have a fixed date in the Gregorian calendar, the key lies in the differing foundations of the two calendars. Twelve synodic months total about 354 days, which is approximately 11 days shorter than the Gregorian year of about 365 days. Without adjustments, the Lunar New Year would advance each year, eventually drifting away from its original seasonal alignment. To keep the calendar in sync with the seasons, the lunar calendar employs a leap month system. When specific conditions arise in the arrangement of solar terms and months, an extra leap month is added to compensate for the discrepancy with the solar year.

For this reason, the date of the Lunar New Year fluctuates between January 21 and February 20 in the Gregorian calendar. The first day of the lunar new year in 2026 falls on February 17, which is simply a result of astronomical calculations. The Gregorian calendar seeks consistency and regularity, while the lunar calendar reflects the actual rhythms of the moon and sun. The differing systems naturally lead to different expressions.

Once we understand this principle, we will not be confused by the absence of a ’30’. The arrangement of time is not arbitrarily decided; it is a manifestation of celestial movements on Earth. The variability of the lunar calendar is a testament to its respect for natural rhythms.

Don’t Look Up: Humanity’s Choices in Crisis

Leave a Comment / Explainers / 胡思

The film “Don’t Look Up” superficially presents itself as a black comedy or tragedy about an asteroid colliding with Earth. However, the true discomfort lies not in the celestial threat but in humanity’s response patterns when faced with clear crises. The film repeatedly reminds viewers that the issue is not one of ignorance, but rather the choice to disregard what is known.

Many have pointed out that the asteroid serves as a metaphor for climate change. Its trajectory is clear, the data has been repeatedly verified, and the timeline is already laid out in models, yet it is persistently delayed, downplayed, and politicized. Much like global warming, the problem has never been a lack of evidence but the stark reality of the costs associated with acknowledgment.

When the two astronomers first enter the White House and clearly outline the timeline and probability of the asteroid’s impact, there is no scientific controversy left. The data is consistent, the models align, and even uncertainties have been accounted for. Yet the first question from political figures is not how to respond, but whether discussing it will affect their electoral prospects. This scene is not exaggerated; it starkly presents a reality: within power structures, the severity of a crisis often must first be filtered through political costs. It is not a matter of misunderstanding but of inconvenient truths.

This distortion is further amplified in the media landscape. When scientific warnings are brought to morning talk shows, rational discourse is quickly consumed by the show’s rhythm. “Don’t be too heavy,” and “Viewers don’t want to hear this first thing in the morning,” lead to the end of the world being packaged as palatable entertainment. When a female scientist breaks down emotionally and cries out, the content of her message becomes secondary; what matters is that she has “lost her composure.” The film’s satire here is chillingly calm: in a media environment that prioritizes emotional management, the validity of facts is often overshadowed by whether the speaker is deemed “appropriate.”

Ironically, when there is already a viable plan with a high success rate to mitigate the crisis, the decision is easily rewritten by a tech billionaire. In his narrative, the asteroid is no longer a threat to be destroyed but rather an untapped source of immense wealth; risk is no longer a disaster to be avoided but a probability to be embraced in the innovation process. The original goal of “saving the planet” is suddenly transformed into a grand scheme of “making a fortune on the side.” As for what happens in the event of failure, it is cleverly obscured, as if simply not stating it clearly will prevent the consequences from occurring. The film mocks not only greed but also a profound arrogance that believes capital and technology can transcend risk itself—an attitude frequently observed in climate policy.

As time progresses, the asteroid becomes visible to the naked eye, no longer requiring telescopes, yet denial enters a new phase. “Don’t look up” becomes not just a slogan but a marker of political identity. As long as leaders say there is no need to look, supporters learn to avert their gaze. At this moment, the film’s focus transcends a single issue, pointing to a more universal phenomenon: when facts conflict with positions, people often choose to protect their stance rather than correct their understanding. It is not that the evidence is unclear; rather, clarity itself becomes unacceptable.

In the end, the world is not saved. There are no heroes to reverse the situation, no miracles to be found. All that remains is an ordinary dinner, where a group of people acknowledges their powerlessness and finally stops deceiving themselves. This scene is poignant precisely because it stands in stark contrast to all previous political performances, media noise, and technological fervor. When all grand narratives collapse, humanity briefly returns to honesty.

The sharpest satire of “Don’t Look Up” lies not in its depiction of a foolish world but in its portrayal of a reality where rationality is systematically suppressed. Here, people are not indifferent due to a lack of evidence; rather, they are paralyzed by the clarity of the evidence, which compels them to change their lives, challenge power, and bear the costs.

As the film concludes, the asteroid arrives as expected. This is not a conclusion but a question: when real-life “asteroids”—be they climate change or other imminent crises—repeatedly loom above us, do we truly not see them, or have we learned to choose not to look up under the guidance of power and money?

Wealthy Yet Short-Lived: The American Life Expectancy Paradox

Leave a Comment / Explainers / 胡思

When measuring a country’s achievements, GDP is never the final destination. The true bottom line is how long people live. When examining this indicator, the United States’ performance is strikingly disproportionate to its wealth status.

First, let’s look at the numbers. The life expectancy at birth for American men is around 75 to 76 years; in contrast, men in other high-income countries such as the UK, Germany, France, and Japan generally live between 79 and 81 years. For women, the life expectancy in the U.S. is approximately 80 to 81 years, while Western Europe averages between 83 and 85 years, and Japan reaches 86 to 87 years. In both genders, the U.S. lags significantly behind its peers, with the gap for men being particularly pronounced, further dragging down the overall life expectancy.

This discrepancy is not due to insufficient healthcare spending. On the contrary, the U.S. boasts the highest healthcare expenditures among OECD countries. In recent years, American healthcare spending has accounted for about 17 to 18% of GDP, far exceeding the 9 to 12% typical of other developed nations. In other words, the proportion of GDP the U.S. allocates to healthcare is nearly double that of some countries, yet it fails to yield corresponding life expectancy outcomes.

The issue lies not in how much is spent, but in how it is spent. The U.S. still lacks a universal healthcare system, leaving tens of millions without any health insurance, while many more have only nominal coverage. Access to medical care depends on employment status and insurance terms. Under this system, illness is not merely a health issue but also a financial risk.

More critically, even with insurance, coverage does not guarantee security. Insurance denials are not uncommon in the U.S., with various technical reasons frequently cited. For the average person, the appeals process is complex and costly, often requiring time, expertise, and even legal support. Consequently, most individuals choose to forgo pursuing claims or are simply too afraid to seek medical help. Over time, the choice to ‘avoid getting sick’ becomes a rational decision.

This is directly reflected in mortality statistics. Numerous studies indicate a significant proportion of avoidable deaths in the U.S.: people do not die from medical impossibilities but rather due to delayed treatment, chronic diseases that cannot be managed over the long term, or the fear of bills that prevents them from visiting emergency rooms during crises. During the pandemic, the mortality rate among uninsured populations was significantly higher, a trend that is not incidental but rather a systemic inevitability.

Even in the absence of immediate death, the healthcare system continues to erode life expectancy. Chronic diseases such as cardiovascular disease, diabetes, and kidney disease, which require stable follow-up, typically imply long-term coexistence in countries with universal healthcare. In the U.S., however, these conditions often spiral out of control due to insurance lapses, denials, or prohibitively high out-of-pocket costs, ultimately leading to premature death.

Ironically, the U.S. does not lack cutting-edge medical technology. It leads the world in advanced treatments, drug development, and specialized medicine. However, longevity is never achieved through the most expensive technologies; it is built on accessible, stable, and affordable basic healthcare. A system that invests substantial resources upstream while imposing heavy barriers at the entry point is destined to be inefficient.

The lag in life expectancy indicates that the issue is not that America is insufficiently wealthy, but rather that there is a fundamental imbalance in institutional choices. When healthcare spending approaches one-fifth of GDP yet still allows people to die prematurely due to insurance issues, denials, and bills, the societal cost incurred far exceeds what any fiscal numbers can explain.
