I have friends who term themselves TigerMoms partly to explain their approach to western friends, but also they have appropriated the name for themselves, there's lots of in-jokes and humour about it. I don't mock, some aspects appeal!
HK schooling was mentioned in the OP which is why I responded to the thread, my point of reference are the HK international schools which the high earning send their dcs. But what you say is true. This, from that blog, explains it better than I can:
"There is a fundamental cultural difference between the East and the West. It is very difficult for the West to understand the East. Vice-versa, it is very difficult for the East to understand the West. Both view education as very important, but it is viewed as TOP priority in the East. The East views education of their children as the ULTIMATE importance worth sacrificing ALL. Not to the same crazy extend in the West. This is seen in our home - being an East-West family. It is very difficult for Florian to understand my craziness. I think I understand Florian, but maybe I haven't quite understand him. I pray that Florian will understand me more in this area, and that I will understand him better too through his cultural len.
The traditional Chinese mom will sacrifice her life - LITERALLY - for the education of her children. In this regards, I am the most traditional Chinese mom of all. I see myself as being poured out, my everything, for the education and development Joshua. The day he is grown up, I will be all poured out and aged. And no, unlike other traditional Chinese, I don't expect anything in return from Joshua. I don't expect any repayment. This is not how I view filial piety. I pour out myself willingly for Joshua with no regrets.
Someone told me that I am paying too much, in terms of sacrifice, in order to do school with Joshua. I would have nothing left for myself. And what about my own personal and professional development? For a working mom, time is so precious. After deducting work time, I do not have much time left. Whatever little time I have left, the majority is spent on Joshua and his "schooling". I have no other choice. I am poured out. I accept it, if I no longer have personal or professional development. Tired as I am, yet I enjoy it so much. I don't have time to myself, yet school time with Joshua is actually time to myself. It is a hobby and an enjoyment. It is a form of relaxation for me."
