The original sentence "If you want to be safe, you must take three points of hunger and cold", which means:

In order to ensure the safety and health of children, we should not eat too much and wear too warm clothes.

From: Wan Mizhai Medical Encyclopedia, a medical book in Ming Dynasty.

Wanmizhai Encyclopedia of Medicine is of high reference value to clinical medicine, and has 10 subheadings, such as Wan's Pediatrics and Gynecological Exercises, with a total volume of 108.

His monograph "Four Essentials of Health Care" has unique views on health care, disease prevention, prenatal and postnatal care and so on. His health theory of "lack of desire, cautious independence, timely treatment of diseases" is not only hundreds of years earlier than the health concept of "psychological balance, balanced nutrition, proper exercise, quitting smoking and limiting alcohol" advocated by the World Health Organization, but also has a more comprehensive, advanced and scientific connotation.

"Wanmizhai Medical Encyclopedia" "If you want to be safe for children, you must take three points for hunger and cold". The background of this book is:

Wan Mizhai was originally a student, but after failing in the exam, he decided to study medicine. Because his family has been helping the world with "medicine" for generations, medicine has a deep family origin, and I am diligent in studying and summing up clinical experience, so his medical attainments are profound, especially in taking pulse and looking at color. Some difficult diseases can be clearly dialectical after his diagnosis.

Wan Mizhai's medical treatment, in addition to inheriting family studies, is based on Neijing and Nanjing, intensively studying Maijing and Materia Medica, focusing on Zhongjing, Hejian, Dongyuan and Danxi, integrating internal medicine, gynecology, pediatrics and health preservation. His medical skills are getting better and better, and he became famous in Qin Long during the Wanli period. Practice medicine all over Luotian, Qishui, Yingshan, Macheng, Huanggang and other places, as far away as Wuchang and Yunyang, and there are many living people.

The county, the government, the Ministry of Foreign Affairs and even the governor and local officials at all levels often ask him to treat diseases. He was once told that the county and the Ministry of Foreign Affairs had given him a "Confucian doctor" plaque. In addition to clinical practice, he is diligent in writing, and most of the works handed down today were completed in his later years. Although Wanquan abandoned medicine and joined literature in his early years, his worship of Confucianism continued unabated.
