I always find the terminology strange. If there is only one party permitted, and that one party is supreme, then how is that a party? It looks like government to me. Maybe the translation to English is just wrong. The "party" isn't a party by any reasonable definition. The real parties would be factions within the so-called party. I don't know if they have names more descriptive than "Xi supporters" and "Xi opponents".
