When I was a child, I was very strict and demanding. I was afraid that my parents would be normal when I grew up.
Everyone is more or less brought up by their parents. Children who are completely or not very concerned are mostly disobedient and unfilial when they grow up. Therefore, parental discipline is very beneficial to the growth of children. You mentioned that parents are still afraid of their parents when they are adults, which shows that the ways and means of parents' education are incorrect, which has caused psychological shadow to children.
