Mute swan cygnets are set to hatch out at North Longhu Wetland Park in Zhengzhou City, central China's Henan Province.

The mute swan is a species of swan. It's less vocal than other swan species, hence the name. With the improvement of the local environment, the park has become an ideal destination for migratory birds to breed. Over the past two years, the number of mute swans in the park has reached 33.
