Why is there only one Luban in China's 5,000-year-old civilization? The saw he invented has been used for 4000 years. What binds China people's imagination and innovative ability?

Because a Luban is a collection of countless carpenters, people first started a god movement to make a carpenter named Luban famous, and then collected all the carpentry inventions that were difficult to determine the creator on him. Therefore, the name "Luban" no longer belongs to a person, but has become synonymous with carpentry since the day it came into being. So the first sentence should be understood as that there are many unknown talented carpenters in China.

The source of many inventions is actually ridiculous and boring. The source of gunpowder is alchemy, the source of inorganic chemistry is alchemy and the source of astronomy is divination. These can all be classified as strange tricks. Once orthodoxy is too strong and there is not enough room for unorthodox existence, creativity will be weakened.
