Is the poem "Grass over the Plain, Come and Go with the Four Seasons" a propositional poem?

This is a propositional poem.

From the Tang Dynasty poet Bai Juyi's ancient poem Farewell to Ancient Grass, the content is as follows

The long grass is so lush that the withered grass will thicken the color of the grass every autumn and winter.

Wildfire can't burn it out, but the spring breeze can revive it.

Weeds and wild flowers are all over the ancient road, and the end of the grass in the sun is your journey.

I once again sent my bosom friend, and the thick grass represented my deep affection.

Comment on the whole poem, the antithesis is neat, the wording is natural and smooth, and it is a propositional poem, but it can be deeply integrated into our lives, so every word contains true feelings. The whole poem is not only decent, but also original, which can be called the swan song in Tuofu.

According to the provisions of the imperial examination, the word "Fu" must be added to all designated topics, which is similar to poetry. Farewell to Grass in the Ancient Plain is to express farewell to friends through the description of weeds in the ancient plain.
