Flower armor means 60 years old. The word "Huajia" comes from the ancient calendar of China, with 60 years as a cycle, and each cycle is called "Jiazi". Because of the various names of branches, it is also called "Huajia".
Another way of saying it is 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 it is called "flower nail". Of course, there are exceptions. For example, people who are in good health still have white marks in their 60 s, while some people are weak and may not have white marks before they are 60 years old.

Song Jiyong's Chronicle of Tang Poetry (Volume 66): "(Zhao Mu) Li Changji, an extra-large middle school student and primary school student in Xian Tong, wrote a short song, saying to wine:' ... Sixty flowers are in his hand, and the cycle is like a pearl. " "
People are used to calling people over 60 "people over 60" and "people over 60". "Huajia" is the abbreviation of "Huajiazi", and the origin of this name is closely related to the chronology of branches 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, Xin, N and G.
There are twelve branches, namely, Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai.
Ten-day stems and twelve earthly branches (odd numbers matched with odd numbers and even numbers of spouses, such as Jiazi and Ugly, but not Jiazi and Ugly) 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 cannot be confused.
So this idiom means to be serious and unambiguous. Together, ten branches are the main ones, starting with "A" and cooperating with twelve branches in turn. By the tenth branch, all ten branches have been matched, so match the eleventh branch from the first branch, and so on, * * * gets sixty groups, which are called "sixty jiazi".
Sixty years goes round and round, so 60 years old is the year of "flower". According to textual research, in the Shang Dynasty in BC13rd century, there was a record of the date of official support in China. It is generally believed that the date of official support began in the thirteenth year of Jianwu, Guangwu Emperor of the Eastern Han Dynasty (AD 54). Before that, the main branches were added by later generations. Chronology of trunk and branch began to be used in the Eastern Han Dynasty.
Named after heavenly stems and earthly branches's intricate name. Ji Gongyou's Chronicle of Tang Poetry (Volume 66): "Li Changji, a middle school student in Xian Tong, has a short song. He said to the wine,' Move sixty flowers by hand, and the cycle is like pearls falling.' "(Zhao Mu)
The year of flowers and flowers is also called the year of hearing.
