Traditional Chinese medicine health care accepted the philosophical thought of Zhouyi and put forward the health care viewpoint of "getting something for nothing". Neijing said: "Ancient people, who knew, learned Yin and Yang, and counted tricks. They lived regularly and didn't rush into things, so they became artifacts and died at the age of 100." Taking "getting something for nothing" as one of the necessary conditions of "never too old to learn" shows its important position in health care. Then, who should we start with if we want to "work hard" in our daily life? First of all, we must "hide the spirit inside." Traditional Chinese medicine pays attention to internal causes, and the so-called "mental internal injury will destroy the body" and "healthy qi should be kept inside, and evil should not be done." The maintenance of true qi is an important sign of human health. Therefore, Neijing advocates that "nothing is indifferent, the true qi will follow, the god will hide inside, and the disease will be safe." Zhuangzi, a Taoist representative who is famous for his health preservation, also has the same quip in "keeping the spirit inside": "If you don't care, keep the spirit quiet and the shape will be right; It must be quiet and clear, you can live forever, get something for nothing, and never shake your essence; Seeing nothing, hearing nothing, and knowing nothing, your God will remain in shape, and shape is immortal.

Pay attention to moderation during sexual intercourse. Lust is human nature, sexual activity is human instinct, and normal sexual life is beneficial to human health, but sexual intercourse must be controlled. If you indulge yourself and overwork your house, you will "consume kidney essence" and shake the root, leading to imbalance of yin and yang, premature aging and numerous diseases. "Qian Jin Fang" said: "Indulge, life is like morning dew." "Neijing" also warns people: "Drunk to enter the room, exhausted its essence, scattered its truth, not satisfied, always resisting God, doing things quickly, contrary to life, then half a hundred will decline." Therefore, paying attention to the maintenance of kidney essence and kidney qi is one of the secrets of longevity. ?
