Benevolence means longevity, that is, virtue means longevity. It is said that people with high morality can live a long life. Confucius was quoted as saying in The Doctrine of the Mean: "Therefore, great virtue ... will make it live longer." The concept of virtue and longevity is the most concentrated and typical embodiment of Confucian health care thought. This is because Confucianism attaches great importance to the role of personal moral cultivation in health preservation, and advocates highlighting the initiative of personal moral cultivation to achieve the realm of moral self-improvement, which is considered to be the basic element of people's longevity. The reason why virtuous people live long is that Confucianism has such viewpoints as "God Blessing Theory" and "Emotion Theory", while the latter is more scientific. Modern psychosomatic medicine theory holds that man is a perfect organism commanded by cerebral cortex. Therefore, psychological factors play an extremely important role in people's health. Moral sense is a kind of social advanced emotion of human beings. Self-moral satisfaction alleviates emotional conflicts and reduces psychological conflicts in this respect, and through the cerebral cortex, it also brings a benign impact on physiological mechanisms, thus benefiting people's health. Lv Mingkun's "Groans" said: "Benevolent people live long and their physiology is finished." In other words, the "benevolent" has all positive factors conducive to the continuation of life in form and spirit.
