书籍是飞机，是火车，是道路。它们是目的地，也是旅程。它们是家。

I look back on the past, committed a felony little fool, I want to communicate with him and let him understand, but I can't do this, the boy would not see the, only my old trunk.

世界是一本书，不旅行的人只读了一页。

History is the shadow cast by the present.

Love is not a profession, it's a condition.
