The pond is full of grass and water, which means that the pond surrounded by grass is full of water.
The title of the mountain is that the sun is about to set, and the red fireball seems to have been bitten by the mountain pass and reflected in the cold ripples of the pool water.
The shepherd boy went back across the cow's back, and the piccolo blew without a cavity. That is to say, the child who brought the cow home sat on the cow's back and played a tune out of tune casually with piccolo. These two sentences are most often quoted to sing the lovely evening scenery in the countryside. The village children are playing flutes on their backs, carefree and innocent.
After reading the ancient poems, we can imagine that the pond full of autumn water, the thick grass on the shore of the pond, the sunset between the two mountains, the shepherd boy holding a piccolo and straddling the cow's back constitute the picture of the shepherd boy coming home late, with pictures and poems. The whole poem is dynamic and vivid. Beautiful countryside in the evening.
