Professor Zheng was born in a family of traditional Chinese medicine. He was deeply influenced by the theory and practice of traditional Chinese medicine since he was a child, and learned and realized the true meaning of traditional Chinese medicine. Besides, he has received modern medical training, and has been engaged in clinical work of gastroenterology and surgery in tongji hospital for many years, so he has a full say in both Chinese and western medicine. Not only that, he also deeply studied and studied Tibetan medicine and other ethnic medicines, and combined his knowledge with practice. It creatively puts forward the theoretical system and operation method of "three links and five elements" for three-dimensional health preservation. In short, it is to achieve the three prime ministers of "qi and blood, meridians and viscera" through the five elements of "drinking, sleeping, communicating, traveling and eating". In his view, a person is truly healthy only if he has sufficient qi and blood, unobstructed meridians and powerful viscera functions. This theory and method has been popularized in Hubei for three years and has been favored by the majority of middle-aged and elderly friends. Many patients with various chronic diseases gradually reduce their dosage or even stop taking drugs, and some old patients who have to stay in the hospital several times a year cut off their contact with the hospital through self-care. Practice has proved that the theoretical system and operation method of "three links and five yuan" three-dimensional health care founded by Zheng is a set of health care books suitable for almost everyone.
