Peng Zu family has experienced Xia and Shang Dynasties since Yao Di. The Shang dynasty kept Tibetan history, officials worshipped virtuous doctors, and the Zhou dynasty served as a pillar of history; According to Records of the Historian Chu Family, "Peng Zu's family tasted as a wave of Yin Hou, and Peng Zu's family died in the late Yin Dynasty." "Teacher" was often used as the title of clan in ancient times. It can be seen that Peng Zu is actually a clan named after it. Kong Guangsen, a Qing Dynasty man, said in Liezi Mo Lifeng that "Peng Zuzhi lived for 800 years instead of Yao and Shun": "Peng Zu was also the ancestor of Peng. Peng surname country: Da Peng, Qian Wei, Zhu Ji. Dapeng experienced a summer disaster, business was the treasure, and Wu Ding was destroyed. Therefore, Peng Zu was 800 years old, saying that Guo Peng died at the age of 800 is not a real death. "This situation clearly illustrates. The so-called 800-year-old Peng Zu is actually the life span of the great Ponzi Kingdom.

There is also a so-called "small flower counting method", which is explained by its supporters as follows: the small flower counting method originated from the "60-year-old day" and was the time when 60 ancient stars and gods were on duty one by one. People worship the stars in the sky, and the life span of mortals corresponds to the stars, so 60 stars are needed to be on duty in turn every year. According to this calculation, the actual life expectancy of Peng Zu today is 130 years old.

However, there is no objection to the legend that Peng Zu was good at keeping in good health. It can be inferred that, because Peng Zu is good at keeping in good health, and there are many people who live a long life in the clan, which is famous all over the world, the legend of Peng Zu enjoying a life of 800 has gradually emerged and spread to future generations. Therefore, Peng Zu, a clan, was a very representative and famous longevity family in ancient times.

Peng Zu has a great influence in history. Confucius respected him very much; Zhuangzi, Xunzi, Lv Buwei and other pre-Qin thinkers all evaluated Peng Zu. Zhuangzi Deliberately once regarded him as a representative figure to guide practitioners. Qu Yuan's "Songs of the South and Questions of Heaven" also records "What does Peng Keng care about when he is an emperor? What does he want from Yong Duofu?" He is good at diet therapy, so Shou Yuan is very long. Both Wang Yi's notes and Hong Xingzu's supplementary notes mentioned that he can cook a good dish and the chicken soup cooked is delicious. After Emperor Yao tasted it, he appreciated it very much, so he gave Cheng Peng a seal. Historical books such as Historical Records also have records about him; Taoism regards Peng Zu as one of the pioneers and founders, and many Taoist classics have preserved Peng Zu's health preserving theory. Ge Hong, a medical scientist in the Jin Dynasty, wrote a biography of Peng Zu. At that time, the king sent someone to ask him for help. He only said: "I was born in the womb, lost my mother at the age of three, and was exiled to the western regions by dog rebellion for more than a hundred years." I lost forty-nine wives and fifty-four children, suffered a lot and was hurt by peace. Wei Rong was burnt, and I was afraid of dying. The smell is shallow and insufficient for publicity. "

In the pre-Qin period, Peng Zu was a fairy in people's mind. In the Western Han Dynasty, Liu Xiang listed Peng Zu as a fairy, and Peng Zu gradually became a mythical figure.

Wang Xizhi's Preface to Lanting Collection: "It is known that death and life are false, and Peng Qi's mourning is wrong." This "Peng" refers to Peng Zu. In addition, the popular "Su Fu, Ji Zi Peng Nian" wedding couplet is Su Dongpo's talent, Guo Ziyi's blessing, Jichang's many children and Peng Zu's longevity.

Yang Jiong, a Tang Dynasty writer, wrote "Courtyard Chrysanthemum Fu": "It will not end well to surrender the life of Emperor Wen, cultivate the skills of Peng Zu and preserve the spirit of nature." "Tai Ping Guang Ji" wrote him: "Born in the womb, he lost his mother at the age of three, and was exiled to the western regions for more than a hundred years in case of dog disorder. Try to wither as little as possible, lose 49 wives, lose 54 children, suffer a few worries and get a few injuries.
