The opinion optimization design of Swan in Beijing Normal University Edition.
I like the black swan wandering between heaven and earth best. It has thick, black and tidy feathers, a small and smart head, a scarlet long mouth and a slender figure. Everything about it is so elegant and full of vitality. Although the appearance is not amazing, its freedom in the water is desirable.

Black swans are often with white swans. Coupled with the white swan, it is really a sharp contrast. The white swan is like a princess on high, while the black swan is a gentleman with profound knowledge and unremarkable appearance. Look! It floats slowly, splashing rows of small splashes from time to time; It hangs its bent neck and pecks fish and shrimp with its long red beak. When he was full, the black swan looked up, hummed, shook off the water drops and swam slowly to the shore.

The black swan went ashore and swaggered like a pretentious gentleman. It strode thoughtfully back and forth.

Although the black swan is not beautiful, it is very precious and is a national second-class protected animal. It is its ugly color that makes it more distinctive and beautiful. I heard the song of "Kelu, Keli" and saw "Black Wings" roaming all over the sky. It was a precious and pure black swan!
