I recommend actually learning about China instead of spewing nonsense. Here are a couple of books you can get started with to get a bit of an understanding of the subject.

Has it been anticapitalist/antifascist?

Why are you saying that? And also being a capitalist does not mean being a fascist.

Has it been a proletariat-controlled society? No.

Do you get your information about China from western news medias?

Edit: adding "And also" before "being a capitalist"
