Erhai Lake in Dali City, southwest China's Yunnan Province is a popular winter destination, especially for those taking wedding photos. 

The orange-red dawn redwoods stand in the crystal clear blue lake and white seagulls fly around the shore, forming a romantic winter scene that can be found nowhere else. 

Erhai, one of the province's most important freshwater lakes, once suffered from harmful algal blooms. But the authorities and residents have worked over the decades to remedy the situation and protect the environment.

As a result, Erhai has regained its glory.
