So, I have come to realize that this is the best answer when confronted with obvious nong stupidity in China.
You know, when some people talk about you, make openly racist or xenophobic statements thinking that you tingbudong.
These people are who they are because education in China is backward and sucky, far below first world standards in every aspects.
Just give it a crooked smile and be glad that you are not them, be grateful to your parents and to your country for giving you proper education.
