What is the mystery of the world's wonderful book "Lu Ban Shu" and why is it banned?
The Book of Lu Ban was a strange book from ancient China. Legend had it that it was written by a craftsman named Lu Ban. This book contained a lot of magical skills and knowledge, including construction, machinery, carpentry, and so on. It was said that the content of this book was very mysterious, and some techniques even surpassed the cognitive scope of modern science. Therefore, some readers regarded it as a magical heavenly book. There were many reasons why the Book of Luban was banned. On the one hand, the book contained some very dangerous techniques such as using fire to attack the enemy, which could be used to murder others in war and civil strife and thus were forbidden. On the other hand, the contents of this book were considered to be against morality and ethics. Some techniques and contents might involve personal privacy and sexual behavior, so they were regarded as obscene articles and prohibited from being circulated. There were many reasons why the Book of Luban was banned, mainly because it involved politics, morality, culture, and many other aspects.
