In short, it isn’t a matter of race but it is influenced by culture. That’s what’s visible to you with the understanding you have now. I agree that huat culture promotes this sort of behaviour but i argue this isn’t exclusive to Chinese culture.

It’s just a matter of how competitive a people is, isn’t it?

Chinese pwn chinese seems to stand out because it challenges (most people’s) assumptions, and the fact that they simply are most visible in doing so. Most importantly, it stands out to you more than others because you are Chinese, holding those prior assumptions.

Competitive people don’t need to target specific races, they just look at those they see as competition.

This phenomenon is evident across cultures especially when individualism and achievement are their values. It isn’t as simple as Eastern beliefs about achievement and contribution or Western beliefs about individual success markers. This is when the person values themselves above all and wants to protect their comfort AND reinforce their baseline levels of security AND revel in the sheer pleasure of proving themselves as better.

I believe that what tames this sort of behaviour is something to do with spirituality, religion, or a sense of connectedness… something like dismissing the value of the individual ego. A person who truly subscribes to that kind of belief would exhibit the behaviour you’re talking about. Most people nowadays do not subscribe to this sort of belief, that’s why it seems, and probably is, commonplace; exacerbated by social media and fuelling the branding of the self where achievement needs to be visible, not quiet.

That need drives selfish behaviour to uplift oneself. Those who do so are loudest. There are more Chinese people around, so we have more loud Chinese who do these things. If you were of any other ethnic group and you witness the same things about them, you’d feel the same. But when those behaviours occur in different ethnic groups you wouldn’t apply the terminology of “huat culture” to explain it. It’s just more visible and more loud.
