I forgot if it was someone on this forum or Weibo comments section who mentioned that he had “a friend” who went to India and treated the lower caste porter very nicely and gave a very good tip. When they went to the hotel room, the porter not only did not respond gratefully but attempted to rape him! Luckily he is a gym bro and held off the attack before anything serious could happen. Basically, the porter was used to getting treated like dirt and when he got doted on for the first time in his life, he assumed that the Chinese man must be a male prostitute and even lower on the totem pole than he was.
I think that pretty much sums up the sort of mentality China is dealing with here.
