Idiom usage

Formal, as subject and object. With praise.

People are used to calling sixty years old "flower armour" and calling them over sixty.

"The year of the flower." "Huajia" is the abbreviation of "Huajiazi", and the origin of this name is closely related to the branch chronology in ancient China. The main branch is heavenly stems and earthly branches. The heavenly stem is called "stem" and the earthly branch is called "branch", which is a symbol of counting and timing that has appeared in ancient times.

There are ten heavenly stems, namely, A, B, C, D, E, G, G, Xin, E and G. There are twelve earthly branches, namely, Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.

Ten stems and twelve branches (odd numbers match odd numbers, even numbers match even numbers, such as Jia Zi and B Chou, but not Jia Chou and B Chou) are combined into sixty pairs of non-repetitive counting units (the idiom "Ding is Ding, Mao is Mao" comes from this. Because "Ding" and "Mao" belong to heavenly stems and earthly branches respectively, they can't be confused, so this idiom means to do things seriously and unequivocally.

Together, the ten branches are the main ones, starting from "A" and cooperating with the twelve branches in turn. By the tenth branch, all ten branches have been matched, then the first branch is matched with the eleventh branch, and so on, a total of sixty groups are obtained, which are called "sixty branches" or "sixty flowers and sixty sons" and "sixty sons".

Sixty years goes round and round, so 60 years old is the year of sixty. According to textual research, in the Shang Dynasty in BC13rd century, China had recorded the date of official support. It is generally believed that the date of official support began in the 13th year of Jianwu, Guangwu Emperor of the Eastern Han Dynasty (AD 54). Prior to this, the main branches were added by later generations. The chronology of cadres and branches has been used since the Eastern Han Dynasty.
