种一棵树最好的时间是20年前，第二好的时间就是现在。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

Literature is the memory of humanity.

市场永远在变，唯有以变应变。
