Chinese parents can get away with things that Western parents can't. Once when I was young—maybe more than once—when I was extremely disrespectful to my mother, my father angrily called me "garbage" in our native Hokkien dialect. It worked really well. I felt terrible and deeply ashamed of what I had done. But it didn't damage my self-esteem or anything like that. I knew exactly how highly he thought of me. I didn't actually think I was worthless or feel like a piece of garbage.so basiclly they are saying that asian parents are really strict. even though people may not agree with their method they have a reason for what they do. they want their kids to do good and not mess around in school. right here in this qoute it makes it clear how by asian parents telling their kids to do good and school and know they are capeble of getting lower than a A makes it less hurtful when they call theis children trassh.
Asian parents have lots of faith in their children so this is why the kids know how much their parents care about them. So overall is good that the Asian have high expectations of their kids.
