Sun Simiao wrote in Soul Pivot: "Therefore, the wise man's way of keeping in good health must be suitable for the four seasons, harmonious with emotions, and both rigid and flexible. If so, you will not be eccentric and you will live a long time. " Among them, he mentioned that "the four seasons should be cold and hot", which means to adjust one's living habits and health preservation methods in line with the changes of the four seasons. He also advocates "harmony and wealth", and thinks that it is necessary to control emotions and mentality and maintain a good mood. In addition, he believes that "restraint of yin and yang, adjustment of rigidity and softness" points out that sexual life should be properly controlled to avoid excessive consumption of Xie Jing.

In a word, the idea and method of health preservation advocated by Sun Simiao emphasize the importance of "supplementing B to guess blood", which is considered as the key to prolonging life.
