Poetry is written by the poet under the background of a certain life experience, so poetry reveals the poet's environment to some extent. Take Li Yu's ci as an example. In the early stage, he was Li Houzhu (Emperor), and his words were the foundation. Later, he became the conquered, and his words showed the feeling that the good times had passed.
On the other hand, poetry embodies the poet's outlook on life to a certain extent, such as Su Shi's poems, which are broad-minded and bold, showing his broad-minded mind; But Li Qingzhao's works (especially her early lyrics) are delicate and euphemistic.
That's all for the time being ~ ~ ~
