First, because hipsters fear the gods, they are afraid that their children will be at war with their parents and suffer, so they avoid calling them relatives and teach them to do so from an early age. Some fortune tellers have taught them that their children should move their ancestors, otherwise it will be unfavorable. How can you give your children to others? We have to change the name, and change it to aunt and uncle. If the conflict is not serious, the names of parents, brothers and sisters are generally used instead, such as aunt Abel; Seriously called uncles and aunts; The most serious thing is to be a child and give it to the gods for protection. In order to keep their children alive, parents call their parents that way when they are young, and they still call them that way when they grow up. It's natural to get used to it.
Second, "Mom and Dad" is a northern dialect, which is elegant. Except for cities and learned families, or "mom and dad", rural people rarely use such words, but do as the Romans do. Some sons of overseas Chinese call their parents "ABBA (bottom voice) and AMA (top voice)", which is a transliteration of "mom and dad".
Third, family planning is late and there are many children. Call them aunt directly, hehe, cheat those who grasp family planning.
