Mathematics is not about numbers, equations, computations, or algorithms: it is about understanding.

The world is so full of simple, obvious, and beautiful things that it's a wonder anyone ever bothers to invent anything at all.

The more you give, the more they take.

表演就是活一千次生命，感受一千颗心合而为一的跳动。

世界上充满了看不见的伤口。
