The pond is full of grass and water.
The mountain topic is cold in the sunset (yι).
The shepherd boy went back and stepped over the cow's back.
Piccolo has no cavity. This poem uses images such as grass, pond, mountain, sunset, shepherd boy, cow and piccolo. And write about the scene where the water plants grow all over the pond, the water slowly fills the pond, the mountain seems to drown the water waves with the sunset in its mouth, and the shepherd boy sits on the back of the cow and plays the piccolo freely.
