Not very true at all I might say. Chinese immigrants are just as susceptible to the vices as anyone else. As for serving as a model on how to behave in a host country, go to Chinatown and look at how dirty the place is, any Chinatown. I have already stated the facts about how many Chinese who immigrate will refuse to learn English (just like some expats on this forum who do not learn Chinese) despite living there for many years. I suppose ugly behavior does have its universal traits no matter what.
