Sun Simiao, a pioneer of the comprehensive and systematic study of Traditional Chinese Medicine (TCM), is revered as the "Medicine God" or the "King of Medicine" by Chinese people. He was a great medical expert of China in the Tang Dynasty (618-907).

　　Sun is said to have studied hard and mastered several Chinese classics by the age of 20. He did extensive research on ancient medical classics, and according to historical records, in the history of TCM, he had particularly innovative views on medical ethics, gynecology, pediatrics, acupuncture, and other topics. Sun held noble medical ethics in high regard, and his perspective on medical ethics was pivotal in the history of Chinese medicine. From his point of view, the doctor's sole responsibility is to relieve patients' pain without being influenced by a desire for reward, such as financial gain, fame, or favors bestowed upon them. Patients should be treated fairly, regardless of their rank, wealth, or other eternal factors, said Sun. In his well known book Qianjin Yaofang, he proposed that a good doctor should place equal emphasis on medical ethics and skills.

　　Sun's experience with herb formulas and knowledge of medicine was documented in Qianjin Yaofang. The book presented life-saving remedies as well as case studies on acupuncture, massage, diet, and exercise. Sun wrote a second well-known book, Qianjin Yifang, as supplement to his earlier work. Both of the books are still in print today, as part of the Qianjin Fang collection.

　　His writings focused on the treatment of women and children, with special volumes devoted to female disorders (including pregnancy), infant diseases and breastfeeding.

　　Sun's research on health care was highly insightful. In terms of his overall health philosophy, he believed that people should combine massage therapies, physical exercise, and breathing exercises. He advocated disease prevention, emphasizing the importance of "caution in a speech before sleep" and "moderation in eating."

　　Sun was described as a "magnificent teacher of hundreds of generations" by Li Shimin, Emperor of the Tang Dynasty. Some of Sun's revolutionary ideas can be used as a reference for current medical development, and his nurturing method for health still remains popular among people of all ages.
