In the past, it was very common for people to take nicknames for the purpose of blessing and eliminating disasters. The main wishes were nothing more than health, longevity, wealth, dignity and so on. Nicknames like centenarians, Zhuang, Afu and Fazai were everywhere.
Some can be selected according to their looks. For example, children who are dark can be named Xiaohei, and those who are fat can be named Xiaopang, which is simple and easy to remember.
You can also choose according to the ranking. Compared with the second child at home, you can choose the baby names as Erbao, Erya, etc., which are common in life. The baby names don't need to be official names, and they don't go to the household registration book, which depends entirely on your personal wishes.
