The relationship between eight-character drying and other seven words comes from that book.

Excuse me, the question you asked is "which book does the relationship between the eight-character Japanese stem and the other seven words come from?" The content of this paper comes from two books: Yuan Hai Zi Ping and San Tong Ming Hui.

Yuan Hai Zi Ping written by Xu Ziping in Song Dynasty is one of the earliest classic works of numerology. The book expounds the functional relationship between the eight-character Japanese stem and the other seven characters, which has become one of the theoretical foundations of the eight-character numerology in later generations.

Sanhui is written by Wan in Ming Dynasty, and it is also one of the important works of eight-character numerology. The book discusses in detail the relationship between the eight-character sun stem and the other seven eight characters, and deeply discusses the combination of various life figures and the changes of fortune.
