Qinghai Lake, the last tear of the Earth~

Qinghai Lake, the largest lake in China, is hailed as the last tear of the Earth, the last tear of the sky... Recently, I took a trip to the Northwest, and when you come to the Northwest, Qinghai Lake is definitely a must-visit! On a sunny day, after the sun's angle lowers in the afternoon, looking at the lake from different angles, sometimes it's sky blue, sometimes it's emerald green, like a moving gem~ tips: Wherever you go, please do not litter and protect the environment
