中国の反日デモ

> But I can still understand what do the Chinese want to show through their actions.

For starters, your use of "do" is wrong. You HAVE to be a Chinese to be making such elementary mistakes.
Forgiving you all your stupid grammatical mistakes and your ignorance of facts, let me ask you how you feel about the atorocities attributable to the Chinese re: the Tibetans, the Indians, the Vietnamese, the Turkistanis, and historically the Koreans.
I'd strongly urge the Chinese to stop acting like beggers and to be more productive - give something to the world; what has China contributed to the world since the Opium war? Prostitution? Cheap labor? Everything I'd call "cheap." Tell me one thing that will make me say that China is a member of the modern world.
