Confucius clearly put forward the relationship between moral cultivation and longevity, believing that "the benevolent live a long life" and "great virtue will surely enjoy a long life". He attaches great importance to the cultivation of moral character, adhering to the principle of "Do not do to others what you do not want others to do to you." "If you want to stand, help others to stand; if you want to be successful, help others to be successful." "A benevolent person loves others," and strives to "comfort the elderly and care for the young." Advocating respect for the elderly and care for the young, and condemning the act of abandoning the elderly, it is said that "abandoning the elderly for the young is an ill omen for the family." By cultivating virtue in this way, one's heart will be free from desires and desires, the mind will be broad and open, and there will be many blessings and benefits. One's potential can be tapped and one's quality can be improved. Moreover, if everyone values virtue, society will be peaceful and people will live in a pleasant and contented atmosphere. Therefore, the ability to benefit oneself and prolong life will not be a problem. Great virtue is bound to live a long life, and there is a practical basis for this in history. According to Wang Chong's "Lunheng", King Wen was 90 years old, King Wu was 93 years old, Emperor Yao was 118 years old, and Emperor Shun was 110 years old. These are all examples of "the benevolent live a long life". Confucius' long life was also closely related to his great virtue. Cultivating virtue for longevity has had a profound influence on later generations of health preservation experts and medical practitioners. For instance, Ji Kang's "Treatise on Health Preservation", Ge Hong's "Baopuzi", and Sun Simiao's "Thousand Gold Prescriptions" all place great emphasis on cultivating virtue for longevity.
