What are the two major systems of physical health preservation in ancient China?

After thousands of years of practice, China's traditional health preserving theory has gradually formed a systematic and complete theoretical system. In this theoretical system, China's traditional philosophy of Yin-Yang and Five Elements, Qi monism and holism are the leading ideas, and the theory of essence and qi and the theory of zang-fu organs and meridians are the theoretical basis, and to some extent, the new ideas and contents of modern medicine, physiology, sports training and other related disciplines are integrated, thus forming the theoretical framework of China's traditional health preservation.
