Watching the swans, writing about them and painting them, besides taking photographs is now common and Rongcheng now annually enjoys a winter "swan tour" boom.
Now, in addition to the swans in Yandunjiao, Swan Lake, Sakura Lake, Sanggou Bay Urban Wetland Park and Shidao Bay, you can also see black-tailed gulls and other birds.
The swans are a part of everyday life in the city, and their images are everywhere - from small souvenirs, paper-cutouts, on stones, and there are many homestays that are themed on swans.
The presence of the swans is mainly due to the improved natural surroundings.
