"Thirty-two years of Zuo Zhuan Xi Gong" said: "What do you know? Zhongshou, the wooden arch of your tomb. " Don Kong Ying Da and other "Justice" clouds: "Life is 120 years old, life is 100 years old and life is 80 years old."
The Book of Health Preservation says: "The Yellow Emperor said: Life is 120 years old, life is 100 years old, and life is 80 years old."
"Zhuangzi Stole Foot" said: "People live to be 100 years old, 80 years old and 60 years old."
"Taiping Jing Jie Cheng Fu Ji" says: "Mortals have three lives, which should be three qi, and the life of the sun and the moon is also neutral. Life 120, life 80, life 60. "
Article 10 of Lu's Spring and Autumn Annals Meng Dong Ji says: "People's life span is only one hundred years old, and the middle life span is only sixty years old."
At present, it seems that taking 60 as the lower limit of longevity age is too low, and most people do not necessarily agree; Although there are people over 100 years old, there are very few in the end; As the minimum age for longevity, 80 years old can be understood, recognized and accepted.
