He recorded in the legend of the birthday girl in China that Peng Zu lived 800 years and was the oldest old man. Did you really live 800 years? It's hard to prove and hard to believe. However, according to the records in Guoyu and Shiji, Peng Zu really existed and was famous for his long life. Ge Hong, a medical scientist in the Jin Dynasty, also wrote a biography for Peng Zu. It is said in the book that Peng Zu lived 700 years at the end of Yin Dynasty, and the King of Yin specially asked him to introduce the way of longevity. Peng Zu's life-prolonging regimen has the following four aspects. First, pay attention to exercise. Get up early every morning, sit up, rub your eyes, massage, rub your lips and pharynx, stay in your abdomen and inhale for dozens of times; Then he got up, stretched himself and worked hard with luck. He was the earliest founder of Qigong, and this fitness method was written as "Peng Zu's Guidance Method" by later generations. Second, it is ideological cultivation. He never cares about fame and wealth, does not pursue material enjoyment, and is quiet and philosophical. King Yin gave him 10,000 gold, which he used to help the poor and left nothing for himself. Get rid of the burden of "smearing Shen Xi" and always maintain a good mental state. Third, it is living habits. He insisted on letting nature take its course without harming his health, paying attention to keeping warm in winter and enjoying the cool in summer, so as to make his body comfortable and healthy, paying attention to the combination of work and rest, avoiding excessive use of his brain, seeking suitable clothes instead of flashy clothes, and rationally adjusting the life and diet of men and women, and said, "All these things, such as water, are harmful if used excessively." Peng Zu, the legendary Jianmingkeng family, is the grandson of Wu Hui of Zhu Rongjia and the third son of Lu Zhongjia. According to fairy legend, these thirty pits are "quiet and heartless, disrespectful, and do not decorate their cars and clothes, but cultivate themselves." He is a doctor, but he often lives in seclusion due to illness, does not participate in political affairs, often travels alone, does not ride horses, "or hundreds of days, dozens of days, does not hold food." Because of his profound cultivation, "270 years old is considered to be 50 or 60 years old." This 30-year-old man is said to have lived to the end of Yin Dynasty, "living to 767 years old, but not aging." It is said that this 30-year-old pit created a pheasant chicken soup with five flavors, which was given to Yao Di, and Yao Di greatly praised it. Therefore, Yao made him a vassal of Emperor Peng. Qu Yuan's "Songs of the South and Teana" has the saying that "Peng Keng has been immersed in the emperor and lived a long life". The descendants of this 30-year-old son have become the ancestors of the Da Peng family, so he is called "Peng Zu". So Peng Cheng is now in Xuzhou, Jiangsu. According to official records in Xuzhou, "Tang Yao named the master Pengguo, and its city is at the foot of Dapeng Mountain, 30 miles away from the city." There is a poem circulating in Laopengcheng: "Wu Yong is good at tasting the ancestors' Pengkeng, and the three squares seek the ancient Pengcheng learning. The princes of the Ninth Congress were ministers, and the princes had eight episodes and five baskets of banquets. "
