> All presidents rise to power on a message of anti-corruption

You mean in China specifically? Otherwise there are some pretty harsh counterexamples to that "all".

I'm just talking about China, we were only talking about China right? We don't really have a lot of data points to go by since there have been only three presidents so far with supreme power (after it was combined with General Secretary and military chair head, before that president was more of a ceremonial role).
