People in xin jing I just watch a historical TV program, It is about 馬騰(ma teng)西涼軍(xi liang troops) in three kingdom. Why are they so strong? Because their battle array came from Roman Empire. A branch of military come to The west of China and live there. So they are different from han nation( chinese?) So they want to separate from China but they use terrorist means and some now join in ISIS. And In historcal, yellow emperor fought with chiyou who is miao nation's ancestry. It look like ghost in chinese history now. It look like yellow emperor is chinese ancestry only. So miao nation want chiyou to be chinese ancestry as well. But miao nation look indifferent from han nation. They just have different clothes from han nation. I think chinese eat bug like spider centipede snake...so on that come from their culture. But han nation feel strange as well. So the different reflect a lot It is better that dont eat snake nowadays because some snake have parasite inside it which like to go to humen brain and one of parasite like bite humen's nerve that is popular there. Some american got it to USA, I watch it from discovery
