There is a cupboard at home, and there is a book called "Lu Ban Shu" in it. What is this?

According to legend, Lu Ban Shu was written by the carpenter's ancestor Lu Ban Ye. This book collects Lu Ban's life skills, some of which are illustrations of furniture making, tenoning, digging, painting and hanging roof truss beams, most of which are about winning. Aversion to victory is a curse method, which means cursing and suppressing. In ancient times, the carpenter Moshi Normal University knew this technology. If you put evil town things on the roof of the house or bury them somewhere, the house will be doomed, destroyed or even destroyed, which is extremely vicious and unpredictable. On the contrary, if auspicious things are put on, the family will get rich safely, increase wealth, and so on. It is auspicious to win money and be tired. For better or worse, it is a kind of witchcraft. According to legend, the carpenter and ink man who has studied this book will have misfortune on the one hand, either lacking arms and legs, or losing incense, or suffering from his family. So this book is also called Lost Door, which is as fierce as the five ghosts in the door.
