What do you mean by age?

Flower armour means that a person reaches the age of 60. This is related to the ancient chronology of China. Ten heavenly stems and twelve earthly branches are interwoven into sixty units in turn, and each stem represents one year, and repeated for sixty years to form a cycle; There is a saying, obedient at the age of 60, and obedient is also used to refer to sixty, just like Huajia, so people often say that the year of Huajia and the year of Shu Shun are the same meaning.

Sixty-year cycle

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".

The twelve earthly branches correspond to the zodiac respectively. Son: Zodiac mouse; Ugly: Zodiac cattle; Yin: Zodiac tiger; Thumb: Zodiac rabbit; Chen: Zodiac dragon; Rudder: Zodiac snake; Afternoon: Zodiac horse; No: Zodiac sheep; Shen: Zodiac monkey; Hey: Zodiac chicken; Hey: Zodiac dog (dog); Hai: Zodiac pig (tapir). In addition, the twenty-four solar terms are divided into twelve earthly branches, and the length of every two solar terms corresponds to one earthly branch.
