Mandarin being a problem is the entire point.
China doesn't want the world to be Chinese.
the rest of the world are barbarians in the Chinese imagination.
China is not the West, it doesn't want random Iranians and Indians and Africans to start idolizing it or fashioning themselves as proto-Chinese.
To be frank, You're an Iranian who lives in New York but constantly bashes it, and doesn't leave. China doesn't want random Persians doing that in Shanghai.
Long Live China as it is now.

Respect is a two-way street. Get out of our waters and stop threatening your neighbours before preaching about respecting 'red lines.'
