在数学中，旅程和目的地同样重要，因为正是通过发现的过程，我们才能真正学习。
In mathematics, the journey is just as important as the destination, for it is through the process of discovery that we truly learn.
临终前与诸同志谈话，1925年3月11日

Childhood is a foreign country we've all visited but can't quite remember.
梦想需要勇气，更需要行动。
The everyday is always extraordinary if you look closely enough.
Your voice can change the world.
