Rongcheng, Shandong province, is located at the easternmost tip of the Shandong Peninsula, and it is home to the winter habitat of the Great Swan.

The Rongcheng Swan Lake is known as the "Hometown of the Great Swan" and is an important relay station for the southward migration of the birds.

From November to April each year, the swans fly in from Siberia and other regions, and they stay there in winter. Statistics show that the number of swans there is more than 10,000.

Every winter, more than 100,000 tourists visit the lake.

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.
