You're still wildly over-generalising. Why do you think that the Chinese, or 'Asians' can be categorised together? Why do you think that people from a country will, as a group, behave in an identical or similar way?
Why do you think they cannot? Or do you think that the thing called "culture" does not exist? How people show or do not show grief can and is the cultural thing.
I think you're the only one who understood my comment.
