TIBET ! THE HISTORY BEHIND TIBET AND CHINA (Yongfei Gu)

I don't know whether it is a very suitable occasion to talk about this issue. So, first of all, I apologize about it.
I saw this video on YouTube, and there are quite a lot of commons following it. I think you may figure out what they were saying without my explaination. Actually, after I watched this video, I was very...very...very... exciting, because it is MY country,and the guys who left the commons were attacking MY country.
China is my motherland. I lived there for almost 20 years, I understand the history and the people there quite well. There is no doubt "Tibet was,is and will a part of China".
Anyway,I am really proud of my motherland.
