In ancient China, it is said that there was a long-lived old man, Peng Zu, who lived 760 years. He was a subject in the ancient Yaodi era, with his surname Qian and his first name Keng. That is to say, in the folk New Year picture "Three Lines of Fulu Hands", there is a young girl with a silver moustache and a sprightly spirit, and a longevity birthday girl. At the end of the Yin Dynasty, he was 767 years old but not aging, which aroused the interest of the Yin king and sent people to ask him for advice on how to live a long life. Peng Zu talked about his views on keeping in good health. Whether Peng Zu really lived for more than 700 years has been difficult to verify, but Ge Hong, a health expert in Jin Dynasty, made a biography of him. At least, Peng Zu's way of keeping in good health represents the generalization of people's understanding of keeping in good health before the Jin Dynasty. Peng Zu's health secret includes the following aspects.

Health God: It is said that Peng Zu is quiet, takes a philosophical attitude towards the world and pays attention to health God. Peng Zu warned people never to hurt, distract, anger or defeat God. He said, "Worry hurts the soul, and anger dispels it." He believes that a powerful god lives forever, while a powerful qi is easy to die. Only by maintaining a good mental state can we be strong and healthy.

Willing to be indifferent: Peng Zu believes that people who are good at taking pictures should rely on self-cultivation and be indifferent. He said: "The husband is warm in winter and cool in summer, without losing the sum of forty, so it is suitable for the body; Beauty and wealth, leisure and entertainment, not the feeling of desire, so God also; Automobile service dignity, contentment is always happy, so there is ambition; Eight tones and five colors are pleasing to the eye, so they guide the heart. All this is to support life. " He warned people not to indulge too much, but to pay attention to the moderation of life, which is "the essence of life."

Peng Zu believes that the reason why a person can live a long life lies in paying attention to ideological cultivation and forming good living habits. As for the technology of breathing and guidance, it is in a secondary position.
