I'm white so don't have any personal experience, but my partner is a brown immigrant to the UK and has experienced nothing even remotely close to that anywhere she's been in UK or Europe.
There is your occasional nutjob small business owner that also kicks foreigners out, but that’s actually quite rare.
But this is the racism that Western people suffer. Chinese people, especially mainlanders, are targetted quite badly.
I will not lie - the moment that you are perceived as Chinese, a lot of people can become assholes. Unfortunately, there is way too much nationalistic propaganda around.
But it’s also a place full of amazing people too. People who will appreciate you for what you are. I wouldn’t write off the whole country. But you do have to develop a thicker skin, unfortunately.
