From what I’ve both read and experienced on a brief trip to Shanghai, it seems there are two main factions - the Beijing faction and Shanghai faction. The latter is more capitalist and chill, the former more authoritarian. It’s probably more complicated though, with multiple sub factions around different leaders in the CCP. Maybe someone with deeper knowledge can elaborate.
