This may be a one-off thing, but I remember playing an online trivial game with some Chinese post-docs. They had no idea who Chung Kai-Shek was! It was almost as if pre-CCP history didn't exist.
Chung Kai-Shek is the romanization of 蔣介石 in Cantonese. If those post-docs weren't native in Cantonese, there's almost no way they can connect the pronunciation of Chung Kai-Shek back to 蔣介石.
In another romanization system used by ROC, 蔣介石/蔣中正 is Chiang Chieh-shih/Chiang Chung-cheng. Mainland Chinese can probably recognize them, but no guarantees.
