… Are you sure it will only be four weeks? Sounds to me like your grandparents really want you to just stay there forever. Since traveling & living long-term (say a year or more) will be very different especially if I’m politically active

I did just go back to China for two months and was fine; lived in Beijing too so there’s that (I think ppl in the South are less… monitored). China is huge… so if someone just minds their own business the authoritarian government (and probably 99% of the population) basically just leaves them alone. But then I also am not very social & most of my family circle are neutral-/anti-China so… If for any reason I offend the government or anyone affiliated who reports me, then I’d probably be done for, and I’m afraid it is bound to happen if I stay there for too long

So yeah, I dunno but I would never stay in China long-term if I were you. Traveling is fine but I really don’t know how to make of your aituation
