Hi dear @yeolmo26.
Greetings to you. Hope you will be fine. GOD bless you. You have very well explained about the advantages and disadvantage of the strictness of the parents. As parents love their children with the core of their heart but they want to improve their personalities but at the same time they forget that over strictness is not good for children's mental health and also physically. In this way the children became rude and aggressive which disturbs their studies too. Best of luck for contest.
