Can you explain what you mean by Communist Chinese? What part of the economic or political structure of China is Communist?
For that matter, what is Communism, in your opinion? How is it manifested?
If you have to ask “why” it is Communist China, ChiCom, Communist Chinese....there is no hope for you.
You should read up on Lenin’s “New Economic Program” for the USSR and all the similarities with that, and, the current situation in Communist China
