On a frozen lake inside Yuanmingyuan (Old Summer Palace), seven newborn black swan cygnets are enjoying themselves with their parents. 

Their presence brings vitality and excitement to the park, attracting many visitors to watch and take photos.

Workers are cleaning up dirt and weeds at the lake of Qianyuan area in Changchunyuan (Garden of Eternal Spring) as part of water ecological management.
