You have good and valid points, especially the calling out of chauvinism. I would like to highlight a few points in your posts, still.

China is a country of people

Is something which is true, but which is problematic in the sense that nation states are problematic and in the sense that Marxism is internationalist. China due to its productive forces has a lot of more ability to withstand a militaristic capitalistic siege than other nation actors had before. Still an end of classes means an end of nation states, sooner or later. This is not to be a critique of China vs any other nation, in fact the US should be unmade before any talk about China as a country should even start.

Like all governments and economic systems should [do to prosper]

Is something I would say is an idealistic view of the goal of governments and systems. The class struggle and the excesses of a bourgeoisie state are what shapes more than the drive to "prosper" what happens in typical capitalistic states.

Still if your understanding of Marxism and Socialism is differentiated you can fit China into Socialism and socialist stages. Naturally there are different points of views of how to apply terms, but that doesn't diminish from that fact.

That real existing China isn't how some utopian young western Socialists imagine Socialism is true, but doesn't matter and often shows their chauvinism.
