I am not Chinese, but came from the country that University degree is normal.
My parents were both working parents, but they made sure that I revised everyday from start of school. I had homework everyday, and they made sure I done it. By the time I was about 10, I didn't need any push from my parents. I just done it anyway, because I realised it helped me progress and get better results at school.
I have been doing the same with my ds. I make sure he reads everyday, and do some revision .(or anything which interests him.) I try to find the resources which reinforce the learning at school, and provide it for him. I'm hoping he will be the same as me, realise that if he works hard, he can get better understanding at school.
With homework from school, my ds still needs bit of reminding, but he knows he has to do it, because I always told him he had to do it like it or not, there was no option. I think people saying primary children shouldn't have home work is a very British thing. Maybe not KS1, but KS2 is quite capable IMO.
