舞蹈是身體的歌聲。

I believe that every story is a kind of truth.

一個組織的毅力質量決定了其成就的質量。

The beauty of mathematics lies in its ability to simplify complex phenomena.

A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success.

Success is a collection of problems solved.

Don’t worry how or where you begin. As long as you keep moving， your success will be far from where you start.
