It was the director who listened to the nightingale playing in the car during the trip, looked at the leaves falling outside the window in winter and lamented that the present environment was wantonly destroyed by human beings. After constant conception, the work A Green Leaf was formed. In this dance, a girl dances with the leaves, and the leaves keep falling. The girl kept mending the trees, and after she could do nothing, she vented her sadness. Expressed the director's regret and silent cry for environmental deterioration.
