Why was Lu Ban's book written by carpenter Lu Ban banned?

Lu Ban, a native of Lu during the Spring and Autumn Period and the Warring States Period, was a carpenter and the ancestor of China's civil construction and timber industry. He created many practical production tools in his life. It was he who invented the saw. In addition, he also made achievements in military tools. According to historical records, he once built a ladder for Chu State, which was used in military war. However, Mozi advocated loving everything without attacking, and there were still some conflicts with Lu Ban. At that time, in order to prevent Chu from attacking Song with a ladder, he went to Chu to argue with Lu Ban, and finally persuaded Lu Ban.

Luban is very talented in building construction and carpentry, and his invention has brought great significance to the production and life of future generations. According to legend, Lu Ban wrote a book "Lu Ban Shu" when he was alive, which was divided into two volumes. The first volume mainly introduces some contents of architecture and woodworking technology, with specific pictures to facilitate future generations to learn and practice. The second volume introduces many witchcraft and spells in folklore, some of which teach people how to frame others. Luban is a carpenter. Why was the written book "Lu Ban Shu" banned? Look at the first sentence at the beginning. It is precisely because of its feudal superstition that it is regarded as a banned book.

Whether Lu Ban Shu was written by Lu Ban is still lack of textual research, but it is popular because of its fantastic color. Bian Xiao inquired about some information and got a general idea of the next book. The second book mainly talks about some mysterious spells, such as: Feng Shui, life extension and so on. Legend has it that the first sentence at the beginning of Lu Ban's book is like this. If you want to learn this book, you must die first. It sounds a little scary, but these are just legends, which are not credible in Bian Xiao's view.

It is said that Zhuge Liang also studied Luban's life-saving witchcraft, hoping to prolong his life by 12 years, but after all, man can conquer nature, so he finally failed and failed to complete witchcraft. Zhuge Liang's bizarre experience made Lu Ban's art even more confusing. However, Bian Xiao thinks it is absurd for Zhuge to learn witchcraft. It may just be fabricated by people at that time and then spread among the people.

In fact, the status of ancient carpenters was not high, and the class stratification of scholars, farmers and businessmen existed for a long time in feudal society. People are proud of getting fame, but craftsmen and businessmen engaged in business are not paid much attention by society. However, the fantastic colors in "The Book of Lu Ban" have brought a bit of mystery to the carpenter's career, so folk carpenters handed this book down from generation to generation as a tool to maintain their status. There are different opinions on the Internet about whether the spell in the Book of Ruban really exists, but I still don't believe Bian Xiao. As an atheist, I believe in the world view of historical materialism. As for these magic and witchcraft, it is better for everyone to stay away.
