What the GP mentioned is much closer to regional bias/stereotype. In my opinion, it's all about how much alignment a group of people can have while gearing towards making/producing something better. Japan has way more alignment, while everybody else in the crowded Asia is busy with taking a slightly better position and showing off to neighbours. People truly enjoy this kind of feelings.

I don't think most of readers on HN can get and care about mainlanders' feeling of being somewhat offended in this case. So I just chuckled originally. But I hope my comment can supply some context.
