1, Qi refers to the most basic energy and physiological functions that constitute the human body and maintain life activities. Traditional Chinese medicine refers to dry umbilical cord, while "brush" in China's philosophy and Taoism is a mysterious energy of metaphysics, which is different from Qi.

2. Ancient health experts thought that "Qi" and "Qi" were two different concepts. "Play" is the initial innate energy of human body, and "Qi" refers to the energy generated through acquired breathing and diet. Qigong exercises mainly connect the innate "qi" through acquired breathing and other methods, so as to achieve the effect of strengthening the body and prolonging life.

3. "Play" and "Qi" both come from the ancient word "Qi", which means cloud gas and hieroglyphics. It also means breathing and smell. Before the Tang Dynasty, there was no difference between the two. Later, Taoism used "play" to represent nature, which is the source of all life and things, and used qi to represent the day after tomorrow, so the meanings of the two were separated.
