What ancient books should be taught by experts?

This is a book about Taoism, which is about the magic that Taoism uses to do things! It's a manuscript, and the paper used is leather paper made in southwest China. The paper is relatively new and not long. You can go to the Republic of China at the earliest! The current market value is about 100 yuan! However, the handwritten font of this book is very good, and the content is ok. It should be sold at a higher price, and it needs to be re-priced after seeing the real thing!
