That’s gotta be pretty out of date. only 22% of native shanghainese people speak shanghainese according to google. I have no idea if that’s including the migrants, if not the percent would be even lower. Right now foreigners are getting looked down on for just being foreigners, don’t forget chinese actually think this is a foreign virus. although i’m sure its not as bad in shanghai, the foreigner stronghold.
not only that, the whole of china is under beijing time, Taiwans time zone is a hold over from china i would assume, does anyone actually know the real history of it?
