I am reading the biography of Deng Xiaoping by Ezra Vogel. In the biography, it mentions that Deng Xiaoping once broke his leg playing billiards. I personally find that highly unlikely. Billiards is not a dangerous sport. It seems more likely that this was an excuse to avoid going to meetings in which he would be forced to take a stance one way or another. Is there any evidence to back this up? Or perhaps he really did break his leg?
