If you want to prolong your life, you should not only take appropriate health care measures according to your personal situation, but also pay attention to your own moral cultivation. Regarding the relationship between morality and longevity, Sun Simiao, a great medical scientist in the early Tang Dynasty, made it very clear in "Thousands of Women": "Lack of morality, taking jade liquid pills, can not prolong life." "Moral Day is full ... and it is a self-extension that does not seek longevity. This is also the great purpose of health preservation. "He listed moral cultivation as the top priority of health preservation, which shows the importance of moral cultivation to longevity. Huangdi Neijing describes this more incisively: "The heart is the palace of the monarch, and the god is outside. "If you are in charge of the Ming Dynasty, you will be safe. If you are in charge of health, you will live longer. Ignorance is the danger of the zodiac. " This passage explains the influence of human psychological factors on disease and health. Many human diseases are even mainly caused by unhealthy psychology. Such as narrow-minded, gloomy and sad, joyful and forgiving, anxiety and fear, jealousy and suspicion, lack of self-confidence, etc. It will dampen people's minds and affect their health for a long time. Therefore, if we strengthen moral cultivation, adjust and maintain a good mental state, physiological functions will be well coordinated, which is the relationship between "governing the Ming Dynasty" and "settling down" in Huangdi Neijing.

How to carry out moral cultivation, some thinkers and doctors in ancient China also had a lot of discussions. Gong Yanxian, a medical scientist in the Ming Dynasty, put forward in Shou Shi Bao Yuan: "Modesty can prolong life, harming others and not benefiting oneself", "Filial piety can prolong life, courtesy can prolong life" and "helping the poor and helping the poor". The Key to Laozi's Health Care lists fame and fortune, debauchery, vanity, wealth, taste and jealousy as social and psychological factors that affect longevity. Ji Kang said in "A Thousand Daughters' Prescription" that there are five difficulties in keeping in good health: "If fame and fortune don't go, it will be difficult; if you don't go for pleasure, it will be difficult; if you don't go for emotion, it will be difficult; if you are not interested, it will be difficult. "Although this argument has a long history, some viewpoints have been integrated into our national tradition, such as' forgetting public interests and harming others'. Today, in the tide of market economy, this virtue needs to be carried forward urgently and cannot be eroded by decadent ideas such as money worship and hedonism, which will affect physical and mental health. Whether people live happily or not depends on their mental state. Mr. Lu Xun once said: "I will drop my blood drop by drop on the road of life to feed others." Although I feel thinner gradually, I feel happy. "People with high moral character and integrity will naturally be respected, and they will live a chic, relaxed, happy and youthful life.
