The function of the writer is to disturb the sleep of the world.

True friends are not those who have endless topics to talk about, but those who can stay together without feeling awkward even if they don't speak.

先读经书，再读史籍，以经论史，评论古人史事，就不会与圣贤相悖；研读史籍，再温经书，以史证经，读书目的升华，决不仅为章句之学。

The biggest risk is not taking any risk. In a world that's changing quickly, the only strategy that is guaranteed to fail is not taking risks.
