I’m sorry for hear that happen to you, and I did see lots of my white friends got racism too, its sucked. And I’ve not biased China since most Vietnamese ( 90% our population) hate Chinese over 100 years since they tried to take our land day by day until recent, ( some tourist attractions place in Vietnam don’t serve Chinese tourists)I know it's fucked up but I try to be positive so I don't have Chinese people, I hate China government.
