When it comes to ancient books, which type of book is less determines which type of book has a high collection value, for example, "bing book" should be a relatively small category.

Cao Cao was emboldened by this, and Sun Quan was emboldened by it. The method of fire attack is perfect to Kong Ming. Jiao Yu also wrote in the preface: "He dabbled in many Confucian works since he was a child, and later traveled all over the world to visit high-ranking people, and one day when he arrived at Tiantai Mountain, he met an old Dao, who was wearing a yellow hat, wore black clothes, and had a special long beard with blue eyes, and was meditating under a pine tree. After this old Dao saw Jiao Yu, he called him over and gave him a book, saying, "This book belongs to my master, and I will pass it on to you today." "This book is the Fire Dragon Sutra.
