Laozi believes that "everything is negative and holds yang, and qi is harmonious" (Chapter 42), which means that everything, including people, is composed of yin and yang, and to achieve a healthy state, yin and yang must be reconciled. To achieve harmony between yin and yang, we must have the impulse to be angry. This is consistent with the view of traditional Chinese medicine. For example, the earth's ecosystem, if there is no impulse of air in the atmosphere-wind, rainwater will not be evenly distributed, and droughts and floods are prone to occur.

To be healthy, the human body must have the impulse of essence, and the impulse of qi and yin and Yang Can should be reconciled.

To achieve harmony between yin and yang, we must have the impulse to be angry.

Laozi said in the fifth chapter of Tao Te Ching: "Between heaven and earth, it is still ambiguous, empty and unyielding, moving out." In other words, people between heaven and earth are like a big bellows. How does essence work in the big bellows of human body? "Virtual but unyielding", the operation of essence is virtual and unyielding, which means that essence is invisible and intangible when it runs in the human body, and it is not felt most of the time. Nothing can make it yield.

In other words, the essential operation will not yield to people's orders. You let it go east, it won't go east; If you let it go west, it won't go west. This is a very important point. "The more you move, the more powerful you are." The faster you vibrate, the more you move. Laozi thinks that the faster the bellows of human body moves, the more essence will be dispatched.

Laozi thinks that exercise can make the essence impulse, and the essence impulse can balance yin and yang and be beneficial to health. This is consistent with the viewpoint of modern medicine and sports physiology, which is a materialistic concept of fitness.

It is consistent with the health practice of the broad masses of people, and the really long-term effective fitness method for human health is exercise. For example, we are very cold, and when we go out for ten minutes, people will get hot. This is because exercise mobilizes the essence and accelerates the blood circulation of human body.
