Fine, I would be interested to see evidence of that if you have any. The study you linked was not related, and that doesn't match up with my own experiences with non-American.
Do you have a quote that describes that, because that's not what I saw at all. The basic summary is that while Chinese people tend to evaluate their skills more modestly than Americans, their emotional self esteem is just as high. I didn't see anything analyzing how they value their self esteem, or how it affects their behavior.
