Abstract：Whether giving up fame pursuing to be a pure poet or not, is a quite difficult choice for Tang Xian zu even in his whole life.

This paper thinks that Tang Xian zu's difficult choice is also the reflection of the condition of the enlightment thought in Ming and Qing Dynasty, which was at the turning point from self conciousness to its opposite.
