Five-animal Exercise is a fitness exercise created by Hua Tuo, a famous doctor in the Eastern Han Dynasty, based on the ancient guidance, breathing techniques and the movements and expressions of five animals: tiger, deer, bear, ape, and bird, combined with the theories of human viscera, meridians and qi and blood. Five-animal Exercise is not only a part of Chinese medicine, but also one of China's national intangible cultural heritages.
