Every year in November， nearly ten thousand whoop-er swans fly thousands of miles from Mongolia and Rus-sia to spend winter in Rongcheng， and leave in March thefollowing year. Rongcheng has been dubbed the world'slargest winter habitat for whooper swans and has becomea rare place where humans can enjoy close contact withthe graceful birds.
