Abstract: This paper points out that the consistent spiritual core in poems on history in Tang Dynasty is deep consciousness of suffering which involves dual connotations:outwards' worries about society' and inwards' lament forlife'. The former is built on the awareness of poets' mission for their age, which is expressed by the trinity of worrying about their emperor, their country and their people. The latter is first expressed as worries about life from those who worry a-bout society in Earl and Flourishing Tang Dynasty,and then is chiefly expressed as worries about one's own life and human's ultimate significance in Mid-and Late Tang Dynasty.
