Why does the poet say that the color of early spring grass is better than that of the imperial city?

The poet said that the grass color in early spring is "absolutely better than the willow trees in the city" because the poet thinks that the grass color in early spring is many times better than the willow trees in the city. The grass color in early spring is unique to early spring, tender and full of moisture, symbolizing the renewal of spring returns and Vientiane, and it is not uncommon for willows to spread all over the city. In late spring and March, the color is strong, but it is not so pleasing to the eye.

"Better than smoke and willow, better than the imperial capital" comes from the first poem of the seven-character quatrain "Early Spring Appears in Eighteen Members of the Ministry of Water" written by Han Yu, a writer in the Tang Dynasty. The whole poem is: the sky is like a crisp drizzle, the grass is close and empty. This is the most beautiful season of the year, far better than the late spring of the green willow. There is a lot of drizzle over Jingcheng Avenue, which is delicate and moist as ghee. The grass colors are vaguely connected from a distance, but they look sparse and sporadic at close range. This is the most beautiful season of the year, far better than the late spring in the city of green willows.

Through careful observation, we take early spring as an example and think that the scenery in early spring is superior to that in late spring, which is unique.
