> 姚明有长城这样坚固吗? 一个黑人球员顺便碰撞姚明一下就倒地了。

Do you know what you are talking about? Yao Ming is arguably The best center in the world right now. He never back down from anybody, not even from Shak.

As for 倒地, everybody falls down in basketball games. Have you not seen 黑人球员 fall down when they were hit by Yao Ming? That happens more often than other way around.
