First of all since most of my friends are Chinese and my dad is Chinese, i've never seen they behave like what actually happens in video so i guess it not the majority it only some a small group of people who behave like that. It not necessarily at all to blame it all the whole country and i think it a bit childish to talk about GDP between China and Thailand u cant compare that since your population is double ours!!.
I personally don't have any hatred toward Chinese people my best friends are Chinese and we respect our own culture. We all proud of our country
