What does it mean that the grass grows in February and the willows are drunk with spring smoke?

In February of the lunar calendar, the grass around the village has gradually sprouted and grown, and orioles are flying around. Willow covered with long green branches, swaying in the wind, as if gently stroking the bank. The evaporated water vapor between Shui Ze and vegetation condenses into smoke. Willow seems to be intoxicated with this beautiful scenery.

The original text is as follows:

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.

In a village far from the front line of the war, in the quiet early spring of February, the grass grows and the willows brush the embankment. The poet infected by the pastoral atmosphere wrote this poem because of the joy of spring.
