What is the artistic conception of Li Hua's Impromptu Poetry in Spring?

Improvisation in Spring is a seven-character quatrain, which was written shortly after the Anshi Rebellion subsided. This is a poem describing the scenery. The four sentences in the whole article are the late spring scenery that the poet saw when he passed Yiyang. In the description of scenery, the poet's sentimental and sad mood permeates it. Literally, this poem has nothing to do with personnel, but after careful taste, the poet reflects social unrest by describing natural scenery. It is precisely because this poem has the characteristics of being sensitive to things and hurting things, that is, seeing the big from the small, and the artistic conception is implicit, so it has won the love of readers throughout the ages.
