You're pretty off on classes. Classes are relations to the means of production. The bourgeoisie are the capitalists, owners of capital. Politically powerful people are not "bourgeoisie." In capitalism, the state is under the control of the bourgeoise, in socialism the state is under the control of the proletariat.

Western "democracy" is the dictatorship of the bourgeoisie. Since capitalists own the media, large firms, and key industries, they own the state and control the flow of information. The proletariat is only allowed a say as far as the bourgeoisie allows them.

In China, the proletariat is in control of the state. The people elect representatives, and often these representatives elect further representatives. The people have the ultimate say, and as I showed, their will is expressed at higher rates than bourgeois democracy.

The CPC is not "basically the bourgeoisie." The CPC is not made up of capital owners, nor is the CPC a business, it's the ruling party as an extension of the proletariat.

China is not imperialist. You cannot be imperialist within your own borders, nor does the central government mistreat local or regional governments.

Basically, I think there's a lot you would gain from reading a bit more about this. I know you said you wanted to avoid reading theory, but there's far too much to adequately cover in lemmy comments here.
