China allowed visa free travel for a reason, the delta between western propaganda about China and reality is so big now it can be used as shock therapy.
GFH never separated Chinese citizens from rest of the world because
1 - GFW never prevented rest of the world from visiting Chinese social media, fact that westerners didnt until now is a testment to their own censorship, not GFW
2 - VPN could have been patched long ago, it didnt, because GFW is really a skill check for visiting American propaganda organs, its again a testmemt to Ameeican condition that their propaganda only work on dumb people
