Lu Ban comes from a carpenter's family. Under such unique conditions, Luban has great advantages over other apprentices who study carpentry. At the same time, I have to say that Lu Ban is really talented in carpentry. He can not only master the woodworking knowledge taught by his father in an all-round way, but also spread his thinking and innovate constantly on the basis of what he has learned. So when I was in Luban, I invented many new things and improved some woodworking tools. It can be said that the woodworking industry has developed greatly because of the existence of Luban.
Although carpentry was a craftsman in ancient times and was respected by the people, carpenters were not very happy when they worked for some rich and powerful people. If they meet a stingy host, they are likely to bully others and let them work for nothing. For such a phenomenon, Lu Ban knew nothing about it. In order to prevent future carpenters from being bullied, he wrote metaphysics in the second half of Lu Ban's book, in order to let carpenters have the ability to protect themselves. After all, the ancients paid attention to geomantic omen, so these carpenters can use the metaphysics they have learned to punish these bullies.
I have to say, Luban is really a prescient person, a capable person, so he is respected as a granddaddy.
