Why can't some children call their parents ABBA and AMBA?

Except in cities, children in rural areas rarely call their parents "mom and dad", but mostly "uncle", "uncle", "aunt" and "aunt". This may sound strange or misunderstood to foreigners, but it has become a custom of hipsters. Until now, most rural people still use old habits to call them. Why is this alias so common? There are two reasons: First, in order to keep their children alive, parents have taught their children to call them that since childhood; Some are taught by fortune tellers, saying that children should move their ancestors, otherwise it will be unfavorable. How can you give your children to others? I have to change my name. I used to call my parents that way when I was a child, but I still do when I grow up. It's natural to get used to it. First, "mom and dad" is a northern dialect, but if it is too elegant, rural people rarely use such words or "mom and dad" except in cities and learned families, and 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". Although hipsters call their parents in disguise, when they become parents, they take "Dad! Mom! " I cried. There is a saying in Chaozhou dialect called "Crying Dad Crying Mom", which refers to the name when crying.
