Is the Mediterranean Climate Really the Best for Human Habitation?

People often say that the Mediterranean climate is the most suitable climate in the world for human habitation. Winters are not too cold, summers are sunny, and rainfall is not as frequent as in tropical regions. Indeed, some of the world’s most famous ancient civilizations were born around the Mediterranean Sea. So, there is certainly some truth to this statement. But I’ve been living in Spain for almost four years now and have experienced several full cycles of spring, summer, autumn, and winter here. I’m increasingly feeling that the so-called “best climate for human survival” might only be half right. ...

Seeing Yourself as an Individual, but Others as Labels: The Absurd Psychology Behind Anti-Black, Islamophobic, and Anti-Immigrant Views

In the overseas Chinese community, there exists an extremely surreal psychological structure. They are not just fervent racists, but also subscribe to a kind of incurable “reverse racism”: they not only discriminate against other ethnic groups but also seem to not truly identify with their own deep down; at the same time, they harbor a particular loathing for other minority groups who share similar circumstances and social positions. In the eyes of some Chinese people, it’s as if humans can be neatly divided into different ranks based on skin color, ethnicity, and religion. ...

Spanish Non-Lucrative Visa and Taxes: Filing Requirements, Bank Interest, and Renewal Certificates

Many people with a Spanish non-lucrative visa have a common question: I can’t work and have no Spanish salary or company, so do I still need to file taxes? The answer isn’t a simple ‘yes’ or ’no.’ More accurately: having a non-lucrative visa does not automatically exempt you from taxes. The non-lucrative visa is an immigration status that, in principle, does not permit the holder to work or conduct business in Spain. Whether you need to file personal income tax, however, depends on a different set of criteria under tax law: whether you are considered a Spanish tax resident and whether your income and assets trigger a filing obligation. ...

Using the Definition of Science to Argue Against Fatalism and a Personal God

A Discussion on the Boundaries of Science, Complex Systems, and Empirical Testing Fatalism holds that a person’s life is already written; the belief in a personal god posits the existence of a deity with will and emotions who responds to prayers, rewards good deeds, and punishes blasphemy. These two claims, though seemingly from different domains, share the same logical structure: they both claim to explain reality but fail to offer clear, stable, and repeatedly verifiable predictions about it. ...

Three Years of Raising a Child in Spain: A 'Happy Paradise' or a 'Laissez-faire Trap'?

After raising a child in Spain for three years, my deepest realization is this: the education system here isn’t designed to ‘push’ children, but to ‘sift’ them. It provides a ‘safety net of connections’ for local elites, while for immigrant families, it’s a ’tightrope walk of pure ability.’ 1. A Shift in Responsibility: From ‘Teacher-Managed’ to ‘Family-Supplemented’ This is the most fundamental difference between Chinese and Spanish education. In Spain, the pressure of education shifts entirely from the school to the family. ...

The Meaning Behind 'Not Plucking a Single Hair': A Debate on Individual Rights and the Boundary Between Self and Society

In Mencius: Jin Xin I, Mencius said: “Yangzi’s principle is ‘for oneself.’ He would not pluck a single hair from his body to benefit the world. Mozi advocates ‘universal love.’ If it would benefit the world, he would do it, even if it meant wearing himself out from head to heel. Zimo holds to the middle ground. Holding to the middle is closer to the right way, but to hold to the middle without weighing circumstances is the same as holding to one extreme. The reason for hating those who hold to one extreme is that they damage the Way, upholding one point while neglecting a hundred others.” ...

Do Chinese People Eat Dogs? — The Arrogance and Double Standards of the West

Living abroad, whenever I’m at a party and things get lively, there are always a few people with a sense of ‘superior civilization’ superiority who feign innocence and ask me: “Do Chinese people eat dogs?” Their eyes are often thirty percent curiosity and seventy percent judgment. It’s as if my nod would instantly devolve me from a modern human into a blood-drinking barbarian. I’ve long since stopped rushing to explain. Instead, I smile and ask back: “Do you drink milk? Do you eat veal?” ...

A Comprehensive Comparison of Basic Education in Spain: The Truth Chinese Parents Should Know

Spain has a system of free and compulsory education for ages 6 to 16, covering 6 years of primary school and 4 years of secondary school. 📚 School Hours and Tuition Differences Spanish Public Schools: School hours are from 9:00 AM to 2:00 PM, with 4 classes per day. Education is free. Spanish Private and International Schools: School hours are typically from 9:00 AM to 4:00 PM, with 6 classes per day. The median tuition for private schools is approximately €6,000/year (about 50,000 RMB). International schools cost around €8,000/year (about 70,000 RMB). Costs vary significantly by grade level, region, and school, with differences of up to 1-2 times the median. 🏫 Teaching Staff and Pedagogical Features Teacher absenteeism is relatively high in Spain. A doctor’s note for sick leave is legally binding, and paid sick leave can be granted over the phone. Primary schools generally use a “generalist” system, where a single teacher teaches multiple subjects like English, math, humanities, science, art, and physical education, which may limit subject-specific expertise. Subject-specific teaching only begins in secondary school. The saying “the gym teacher taught my math” is not a joke in Spain but a result of the generalist system in primary schools. Exam scores are not ranked. 🈯 Language of Instruction and Multilingual Environment International schools primarily use English for instruction. Private and public schools mainly use Spanish. Autonomous communities like Valencia and Catalonia require students to learn the local regional language. In secondary school, a second foreign language such as French or German is added, making the multilingual workload demanding. 📖 Workload and Holiday Schedule There is less homework. The academic year is divided into three terms, with a total of about 160–180 instructional days. Holidays are long. 🇨🇳 Comparison with Basic Education in China Public Schools: School hours are from 8:00 AM to 4:00 PM, with 6–8 classes per day. Education is free, with some regions offering after-school programs. Private/International Schools: 8:00 AM to 5:30 PM, with evening self-study sessions starting in middle school, which do not exist in Spain. Private: Approx. 60,000 RMB/year International: Approx. 180,000 RMB/year The academic year is divided into two semesters, with over 190 instructional days. 🏟️ Disparity in Campus Facilities International schools in China often have campuses exceeding 100 acres, featuring heated swimming pools, theaters, multimedia libraries, maker labs, Olympic-standard stadiums, and even equestrian centers, golf courses, and drone and robotics labs. In contrast, Spanish schools are modest and compact, with simpler facilities. 📘 Curriculum and Difficulty Many people believe that primary school math in China is much harder than abroad, but this is a long-standing misconception. ...

A Thousand-Year Turtle? When Will We Stop Taking Things for Granted?

Almost everyone has heard the old saying, “A turtle for a thousand years, a tortoise for ten thousand.” In Chinese culture, turtles and tortoises are seen as symbols of longevity, as if they are naturally destined to outlive several human generations. But here’s the question: Has there ever really been a turtle that lived for a thousand years? Many people see a giant turtle or tortoise and exclaim, “Wow, this one must be hundreds of years old!” While such statements might “sound reasonable,” they actually don’t stand up to scrutiny. ...

Answering Philosophical Questions with Science: A Rational Reconstruction of Time, Meaning, Consciousness, Causality, and Morality

Throughout human history, a certain class of questions has been asked repeatedly for millennia. What is time? Does life have meaning? Must we fear death? Do we truly have free will? Where do good and evil come from? These questions have long been categorized under “philosophy” or “metaphysics,” shrouded in layers of myth, religion, metaphor, and strong emotion. But today, with the advancements in physics, neuroscience, and information theory, we have the opportunity for the first time to— ...

Does AI Have Memory?

When many people use an AI chatbot for the first time, they might feel like it ‘remembers’ what was said before. For example, if you ask a question and then follow up on it a little later, it can still connect the dots. This leads to a common question: Does AI actually have memory? Let’s start with the conclusion: An AI’s ‘memory’ is not the file-based memory we imagine. It relies on predicting with parameter weights, not on hard-drive-style storage. ...

Essential Apps for Blue Zone Street Parking in Spain & Money-Saving Tips for Long-Term Airport Parking

In Spain, commercial parking lots are generally expensive. A few hours can easily cost tens of euros, which is a significant expense. To save money, consider using free roadside parking spots or the paid blue zone parking spaces provided by the municipality. Blue zone parking spaces are cheaper, costing around €1 per hour. However, paying manually can be a hassle. You need to go to a nearby payment machine, enter your license plate number and parking duration, and pay with coins or a card. If you leave early, the refund process is also quite complicated. Therefore, it’s highly recommended to use a convenient parking payment app for online payments and flexible billing, which is more economical and practical. ...

Europe Once 'Lost' an Entire Civilization: Why Did Ancient Greek Rational Knowledge Disappear in Medieval Europe?

Medieval Christian Europe experienced a systematic interruption of Greek mathematics, philosophy, and science due to linguistic fragmentation, the collapse of the educational system, and religious monopoly. In contrast, Greek knowledge was fully preserved, translated, and developed in the Byzantine and Islamic worlds. It eventually returned to Europe through cross-civilizational transfer, igniting the Renaissance. Many people subconsciously assume that: Since Europe is the successor to ancient Greece and Rome, then mathematics, philosophy, and science should have been passed down naturally through the ages. ...

Later on— The ancient Egyptians deified their pets (jackals, cats) The ancient Greeks raised a group of “superpowered giant babies” on Mount Olympus Zeus and his family, instead of doing anything productive, spent their days cheating and bickering. ...
