Li Yu's "Young Beauty" "How much sorrow can there be, just like a river flowing eastward." The beauty of it is that it is very appropriate to use the spring water of the whole river as a metaphor full of sadness and hatred. It not only shows the long-lasting and far-reaching sorrow and hate, but also shows the surging sorrow and hate, which fully reflects the strength and depth of feelings in the Pentium.

Highly summarized and incisively expressed the poet's true feelings.
