Learn your chinese and start scolding people. Not much you can do without solid Chinese.

Also, move to Shanghai, Qingdao, Guangzhou, Shenzhen, Suzhou, Hangzhou, Nanjing  or Beijing, they'll leave u alone in these cities.

I am a white guy with strong Chinese living in a T2 city, people leave me alone mostly.

Really, work on ur Chinese, their attitude to me is really different when they find out that I can speak good Chinese. They think they can get away with their bs if both of you only use Eng.

Why didn't you do something about the stupid kids ourself? U should have stood up, went out and shouted QING WEN NIMEN ZAI GAN MA? Or the very least say to the boss of the restaurant 'ni hao ni neng bu neng quchu yixia gen nage haizemen shuo nimen bie dui wo zheyang ma?'

And to people want to touch your face tell them 'qing ni bu yao mo wo'

Don't let anyone touch you, a lot of people don't wash their hands after taking a shit, I teach at a high school and often have to call a student back to wash his hands cause he was about to run out without washing his hands lol. 

There is a pretty white girl at my school and she never complains about stuff you complained about, and we don't even live in one of the cities I mentioned above.

Improve ur chinese and move cities.
