What is the theme of Jade Flower palace translated by Kenneth Rexroth?

That the future is unpredictable and through years anything can happen. A palace can become a pile of ruins.

to be deep, it is all about Man's mortality in which no can one escape and that is override by time which is the mortal enemy of a human.

No matter how rich, popular, talented and etc., there is no escape. That was Jade flower palace means to me. --6.0--jet
