China has never banned overseas income or overseas investment— it only restricts exchanging domestic currency to invest abroad.

So the teachers who are going overseas have been shouting for ages, and it’s all about the policy being “blown up,” “opening the port,” “opening-harbor cards,” “Singapore cards,” and “xxx cards.”
Not a single person is truly sharing their real, firsthand experience of having their income enter the country.
If you’re not going overseas, aren’t you just acting as a marketing account on X, and then using ad flyers that “connect you with old Chinese contacts,” right?
