Is folk magic true?

China's culture is full of mystery. Folk magic is of course true, but most of it has been lost now. For example, there are Lu Ban Shu and You Zhu Shu. These are all real magic handed down from the people, but ordinary people can't touch them, so you don't know more.

Where are the folk magic books such as Jiulong Bone Water in Lu Ban's book? Xuanqige? You can find it in the library, and there are many other folk magic books, such as You Zhu Art.
