The year of Li Dynasty comes from The Analects of Confucius. The original text is "Stand at 30, don't be confused at 40, know your destiny at 50, listen at 60, and walk at 70 without overstepping the bounds." It means that when a person reaches the age of 100, he needs the care of his filial son in food, housing and other aspects, so "100" is called "Yiyi".
The Book of Rites and Songs compiled by Dai Sheng in the Han Dynasty: "Life is ten years old, learning; Twenty weak and crowned; Thirty is strong, there is a house, eighty is a hole, ninety is a hole, and a hundred years is a lifetime. " It means that the life span is as long as 100 years, so it is called longevity year. Sun Xidan's summary: People who have lived for a hundred years should eat, live and move.
