What is the meaning of the quatrains in ancient poems?

The mountains and rivers in spring look particularly beautiful, and the spring breeze exudes the fragrance of flowers and plants. Swallows are flying around with wet mud in their hands, busy building nests, and couples of mandarin ducks can't sleep in the warm sand. The whole poem depicts the spring scenery full of business and expresses the poet's happy mood of loving nature.

Du Fu [Tang Dynasty]

Jiangshan bathed in spring, how beautiful, flowers send flowers.

Swallows are busy nesting in wet mud and sleeping in pairs on the warm beach.

Appreciation of quatrains

"Spring Breeze and Flower Scent" shows a beautiful spring. The poet "Swallow in the Mud" chooses the most common and distinctive dynamic scenery in early spring to sketch. "Sleeping in warm sand" is in contrast to the dynamic flying swallow in the third sentence, which is dynamic and static, and makes each other interesting. These two sentences depict the flying swallow with mud and the sleeping mandarin duck with meticulous brushwork, and cooperate with one or two sentences to outline the broad and bright scenery, which makes the whole picture harmonious and unified, forming a colorful, prosperous and aesthetic early spring scenery map.
