Describe the mood of sunset in autumn.

1. By the Swan Lake, I saw the sunset. The yellow sun of duck eggs is reflected on the lake like a red ribbon, and there are a group of ducks playing on the calm lake.

2. The color of the clouds beside the sunset changes greatly, from lily to golden, from yellow to red, and from gray to red. In the blink of an eye, he turned into rosewood. Come on, it's really colorful and changeable.

3. With the twilight spreading, the outline of Castle Peak disappears. The light is on, too. My mother and I walked home with dusk.

4. After a while, the sunshine gradually becomes shallow, slowly, slowly, only showing a ray, it is still fighting for its last strength, giving people a beautiful smile.
