"Books say: She did this because. Life says: She did this. Books are where things are explained to you; life is where things aren't. I'm not surprised some people prefer books."
书说：她这么做是因为。生活说：她这么做了。书是向你解释事情的地方；生活是事情不被解释的地方。我不奇怪有些人更喜欢书。
In mathematics, the art of proposing a question must be held of higher value than solving it.
Every mathematical problem has a solution; the challenge is finding it.
相信有时也会受伤。
