Extended data
The ancient age appellation came from different sources, most of them were named according to the physiological characteristics of different ages, but some of them followed the words of their predecessors and became fixed names.
Of all age appellation, the title "ninety" is the most interesting. Or "mackerel back", mackerel is a kind of fish, and the stripes on its back are like the wrinkled skin of an old man. In old age, senile spots appear on the skin, such as the skin of frozen pears, so it is also called "frozen pears".
There are also names based on physiological characteristics, for example, people are called "babies" at birth because they need to be held on their chests to feed them. Babies can pass fake, fake breasts. A baby is a child held on his chest. Seven-year-old is not only called "mourning", but also called "losing teeth", so it is called because it is the period of changing teeth.
