Abstract:Compared with his early years, CAO Zhi's life had changed a lot in his late period. In his early time, he was a self-satisfied and talented man. But later, he struggled in endless depression. And literature is a symbol of depression. Such depressed life would inevitably be reflected in his poems. Out of various reasons, his poems in his late years seldom expressed such depression directly. And comparatively, they took the forms of lyrics, comparison, incarnation and contrast to express his low mood indirectly. It is these indirect ways that made his late poems take the features of feud without annoyance, implicitness, and deep connotation. These are of great help to improve the artistic levels of emotion expression of ancient Chinese classic poems and enrich the artistic experience of such expression.
