Sixty years old is called the year of flower and flower, and it is also called the year of hearing. The year of sixty years is an ancient title, which is taken from the tradition of branch chronology. In the past, each branch represented a year, and 60 years was a round. For some reason, sixty is called "the year of sixty".

According to Volume 66 of Ji Gong's Chronicle of Tang Poetry, "Li Changji, a middle school student in Xian Tong, wrote a short song and said to the wine,' Manually spend sixty flowers, and the cycle is like a pearl falling'." So 60 years old is "Hua Jiazi".

Extended data:

In the ancient calendar of China, 60 years is a cycle, and a cycle is called Jiazi. Because there are many branches and intertwined branches, they are called Jiazi. So what we can know is that the flower is a cycle, 60 years old.

There is a saying that there is a white mark at the root of a person's nail. At the age of 60, with the aging of the body, this white mark will disappear, so the 60-year-old person is called "flower armor".

In addition to sixty years old, those who are seventy years old are called Yi, those who are eighty or ninety years old are called Yi. So "longevity" is Gao Baisui's longevity.
