"Do they say something like Chinese are barbarous,violent,lack of symphasy.etc."
Actually this is what a Chinese man used to say about the Japanese in his emails when he knew about my plans to move to Japan. He kept telling me that the Japanese wouldn't 'accept' me among them. He was a Muslim convert anyway. He didn't like me apparently.
Oh and I found some Japanese people say bad things about South Koreans.
I'm not surprised to see all that. Because that's what is happening in the part of the world I live in
