Tourists have been boarding yachts to enjoy the cool sea breeze and feed black-tailed gulls on Hailyu Island in Rongcheng, a coastal city in Shandong province, this summer. 

The island, which has been dubbed the "kingdom of gulls and egrets", is home to tens of thousands of black-tailed gulls, yellow-billed egrets and wild harbor seals.

Hailyu Island is an ideal destination for travelers eager to get away from the hustle and bustle of the city, and get close to nature. It is also an excellent place to watch birds. [Photo provided to chinadaily.com.cn]
