Originally called "Jingfang Xiaopin", it is a medical prescription work. Written by Chen Yanzhi. It was written between the first year of Xiaojian and the first year of Yonghui (454-473) in Song Dynasty in the Southern and Northern Dynasties. The title of the book "Jingfang" comes from "Hanshu·Yiwenzhi", and the meaning of "Xiaopin" is taken from the Buddhist classic "Xiaopin Prajna" (also translated as "Xiaopin Jing"). The original book has been lost for a long time and has not been published in the past. Most of its essays can be found in Chinese and Japanese classical medical works such as "Waitai Mi Yao" and "Yi Xin Fang".
