Find out two poems describing moonlight in Pipa Xing and explain their functions.

1, "Dong Fangji, we saw Bai Qiuyue enter the river." These two sentences are about the performance effect of pipa girl. Everyone was fascinated, the performance was over, and the listeners were still immersed in the realm of music. There was silence all around, except for a bright moon reflected in the water.

People from the East Ship and the West Ship listened quietly; I saw Bai Yue reflected in the middle of the river.

She has been taking care of an empty boat in the estuary, and she has no companions except the bright moon and cold water. The businessman who wrote these two poems only cares about making money and never understands art and emotion. He often goes out alone, leaving the poor woman at home. People have memories. In the face of today's loneliness and neglect, recalling the past makes it mine. In contrast, how can it not make people feel sad? It highlights the loneliness and bitterness of women.

He left, leaving me alone at the mouth of the river; The autumn moon accompanied me around the cabin, and the autumn water was cold.
