Cunju

In February, the grass grows and the warblers fly, and the willows are drunk with spring smoke. The children came back from school early, so they were busy flying kites in the east wind.

Translation:

In February of the lunar calendar, the grass gradually germinates and grows, the orioles fly around, and the willows gently brushing the shore are intoxicated by the spring fog. The children in the village came home from school early, and quickly flew kites in the blue sky in the east wind.

The first half of the poem is about scenery, and the second half is about people. The first half is basically static and the second half is dynamic. The state of things and personnel set off each other, and the movements complement each other, so that the whole poem is perfectly and harmoniously unified under the theme of "spring" scenery seen in the village.
