In fact, it can be simplified, that is, in Neijing, it is said that moderate diet and regular daily life may lead to the integration of body and mind, thus reaching the end of life. In fact, in a popular way, that is to say, the way of keeping in good health conforms to the natural changes of Yin and Yang, the four seasons, moderate diet, regular work and rest, no rash advance, and no excessive sexual intercourse, so it is possible to live to a natural age.

Nowadays, people often treat wine as water, drink too much, stay up late during the day, go out at night, turn their lives upside down, indulge in excess, exhaust Yin Qi and dissipate their true qi, so they often die young before they get old.

In fact, the road is not far from people. Health preservation is not a profound and mysterious knowledge. Right beside you and me, it's easy to do. The most difficult thing is the word "unchanged". If you can persist, make health care a part of your life, not a task. Enjoy life, not consciously and passively obey it.
