Can a woodbird in Luban fly for three days?

People say it is good to be smart, but people say it is not good to be clumsy. "But I think Mozi is wrong. I'll explain it in detail later. First of all, did Lu Ban really invent the wooden bird? Did you really fly for three days? That is the most important pioneering work in the history of human flight! Even if you can't reach the goal of "the apprentice, it must be three days", as long as you can go to heaven, it is not easy. For example, the "bamboo dragonfly" will go to heaven when its hand is rubbed, which contains the principle of propeller. Another example is the glider, which contains the lifting principle of modern aircraft, which is obviously far from being invented in that era. For example, there are kites and lanterns. Although it is also an ancient plane in China, it is unlikely to be produced during the Spring and Autumn Period and the Warring States Period. And it wasn't cut from bamboo. In a word, I think this is only Mozi's fable. All the pre-Qin philosophers love to make up fables, which are not true, just to illustrate their philosophical thoughts. Mozi is just "extremely clever" and "extremely clumsy" here. First, he said that the cleverest Lu Ban Ye invented a wonderful but useless wooden bird far beyond his time, and then he cited a very simple but useful car harness made by an ordinary carpenter. The comparison between the two leads to Mozi's philosophy that "intelligence" is beneficial to talents and unfavorable to people. No matter how clever you are, you can only use it. And I think: this truth is all wet. This is the difference between China culture and western culture. China people are too pragmatic and lack the scientific spirit of western romantic fantasy. Westerners have the spirit of exploration since ancient Greece and have great curiosity about the mysteries of the universe. The apple fell on Newton's head. If people in China didn't just say "damn it", Newton looked at the moon from the apple tree and discovered the law of gravity. When Maxwell studied electromagnetic waves, he had no idea that it could create a colorful information age, but just thought it was "interesting". There are many absurd inventions in western patent libraries, which make people laugh, but it is this crazy spirit of invention that opens the industrial age. Take the perpetual motion machine that countless people devote their lives to research. Although it will never be successful or useless, there are many ingenious ideas that can minimize friction and overcome resistance. These ingenious ideas finally laid the foundation of mechanical design principles. If Lu Ban can really invent a flying wooden bird, even if it is just a toy, it must contain superb flight science principles, which will be the pride of China. A hundred schools of thought contend is the most open era of China thought, and Mozi is the only scientist among philosophers. Even so, it failed to produce a pure spirit of scientific exploration regardless of utility. Confucius was even less interested in scientific exploration. The so-called "the son is speechless and deserves the blame" certainly shows that Confucius is not interested in ghosts and gods, but at the same time he is not interested in natural mysteries. Confucius only cares about the world, the relationship between people, the relationship between monarch and minister, the relationship between father and son and so on. Confucius' theory eventually became the mainstream of China's traditional culture, and no one cared about the universe and nature any more. Even astronomical observation is only to explore God's will for the son of heaven, so as to verify the good and bad luck of the world. Of course, China people are not skilled in technology, and craftsmen like Lu Ban are constantly inventing and creating, but thinkers like Mozi disdain to explore the so-called "strange skills and cunning", so there is only technology, not science. As a result, China, the boss, is getting older and more decadent, while the curious Europeans remain energetic forever. Today, China people still only value applied technology and direct benefits, and are never willing to invest in basic scientific research that can't be exchanged for cash for a while, so they haven't won a Nobel Prize so far. Alas, it seems that Mozi's "helping others" is greatly wrong!
