Cold but comfortable

This region has a springtime look even in the midst of the chilly winter, thanks to Erhai, the second-largest freshwater lake in Yunnan province, which covers an area of 257 square kilometers. Yang Feiyue reports.

Thousands of snow-white sea birds take to the air whenever food is thrown at them near Xiaoputuo Island in the Erhai lake.

They don't fear the presence of humans. Some even fly toward the food held by visitors and take it away.
