The author is Bian Que, whose original name is "Eighty-one Difficulties in Huangdi's Internal Classic", which is one of the works of ancient Chinese medicine. It is said that it was written by Qin Yueren (Bian Que) during the Warring States Period.

This book is written in the form of answering questions. This paper discusses the problem of 8 1, so it is also called "81 difficult problem".

4. Shennong Materia Medica Classic, as the earliest extant classic of traditional Chinese medicine, originated in Shennong and was handed down from generation to generation. It was compiled into a book in the Eastern Han Dynasty. The book was not written in a moment, and the author was not alone. Many physicians in Qin and Han Dynasties collected, summarized and compiled monographs on pharmaceutical experience at that time, which was the first systematic summary of China medicine.
