I saw an unfriendly exchange between a "Chinese" and a Taiwanese in the square.

I want to say, don't come out and embarrass yourself. As a mainlander, I really don't agree with your remarks. You know the current situation of the mainland very well. Since you can speculate in cryptocurrencies, you should make some money secretly and keep a low profile. Where does the confidence come from to be on the same stage: Taiwanese brothers show their superiority?
