I used to live in guangzhou and chinese people ARE very racist. Some guy actually told me to "go back to England" and I answered him by saying "I'm not english, I'm swedish", then he got silent and left
yeah it's fun though you learnt he chinese slang they use to talk about white people so you know they're talking about white people and then get in their face when you hear them talking about you, it's great, the speed at which they shit themselves
