People often say "the year of establishment", "the year of no doubt" and "the year of know life", which are recorded in The Analects of Confucius: "Confucius said: Five out of ten are determined to learn, standing at thirty, not confused at forty, knowing the destiny at fifty, obeying at sixty and obeying at seventy."

The Book of Rites, compiled by Dai Sheng, a Han Chinese, said: "Life is ten years old, twenty weak, thirty strong, forty strong, fifty ai, sixty, eighty and ninety years old." Among them, there is also the saying that you are guilty for years. But later generations often regard "early learning" and "weak crown" as age appellation.

Age appellation

Age appellation is an ancient name for age. The age of ancient people is sometimes expressed by other titles instead of numbers. Age appellation is mostly recorded in books, and has been used ever since.

The age of ancient people is sometimes not expressed by numbers, not by telling someone's age or age directly, but by an age-related title instead. For example, the total angle is a teenager between the ages of eight or nine and thirteen or fourteen. Because ancient children cut their hair in half and tied it in a knot at the top of their heads, it is called "total angle".
