Good to see a tough Chinese behaves like this.
I remember many years back I was told that black are afraid of Vietnamese
in high school though the Vietnamese are much smaller in size. The main
reasons are Vietnamese are tough and always helped each other in the school.
After the school they often carried weapon(knife and gun) to fight against
bullying happened during the school time mostly from blacks. After a couple
of cases, then blacks warned each other to not do the bad things to the
Vietnamese.
