At the risk of drawing serious criticism and offense,
I’m not sure where you’re from. But you’ll find that most places are not nearly as open and accepting about foreigners as the West is. A lot of my time in China was met with open dislike/distrust of all foreigners (not just a certain country) and this is unfortunately just a fact of life that we have little power to change – except for being good ambassadors of our home countries when we go over.
Chinese dating customs are still very much concerned with concepts of staying within the country (the 外國 vs the 國內) and things like virginity. Some people will still only consider those within their own province.
Even the Chinese girls I know refuse to tell their local boyfriends that they’ve dated a foreign guy before.
Sounds like you’re getting some of your first experiences with disagreeing with another culture. China is waaaayyyy different than the West, hardly comparable. You will encounter many time where you say “I LOVE THIS!” and many times where you say “WTF???” (like now).
It’s part of the learning process I suppose.
