The Luban Sutra was also a strange book, so why did few people know about it?
Lu Ban Jing was an ancient Chinese classic written by Lu Ban, an engineer and inventor from the Spring and Autumn Period. This book recorded Lu Ban's inventions and innovation, including construction, machinery, tools, and crafts. Although the Luban Sutra had a history of thousands of years in China, its exact time and author were uncertain, so it had always been regarded as a fictional book. Due to the fictional nature of the Luban Sutra and the fact that it was not widely circulated in China, there was relatively little understanding and research on it. Even so, it was still an important part of ancient Chinese science and technology and engineering culture, and one of the important documents in the history of science and technology in the world.
