Why is Hua Tuo's "Five-Animal Play" a symbol of the introduction and development of China in ancient times?

"Guidance" is a physical activity, which combines breathing and breathing. In the pre-Qin period, the guiding technique was relatively simple. In the early years of the Western Han Dynasty, the guiding technology developed rapidly, and the technical potential increased greatly, emphasizing the scope of action, and its single-potential guiding treatment technology became mature.
