The wetlands in Yancheng City, east China's Jiangsu Province, is known as a paradise for thousands of rare birds, including the red-crowned cranes under first-class state protection in the country. Recently, in Yancheng Wetland Nature Reserve for Rare Birds, the red-crowned cranes have come for winter, providing photographers many moments to capture.

The red-crowned cranes will stay in the wetland for about six months, and migrate back to northern China when it's warm enough.
