Health-preserving culture is the essence of traditional culture in China, which has a long history and stretches for thousands of years. Traditional Chinese medicine (TCM) has a long history of research on health care. Starting from Huangdi Neijing more than 2000 years ago, many doctors, Buddhists and Taoists have made detailed and profound explorations and discussions on the way of health preservation, and gradually formed a systematic theory of health preservation in traditional Chinese medicine.
