In the early morning, the Hunhe River in Shenyang City, Liaoning Province is rippling and sparkling. Thousands of migratory birds, such as swan geese, ruddy shelducks, and mandarin ducks, are foraging and having a rest on the river while flying towards the rising sun from time to time. They sometimes hover over the water and sometimes swim on the river, forming a beautiful landscape. Every year, thousands of migratory birds fly to the Hunhe River to overwinter.
