Qinghai Lake, also known as "Tsuowenbu", means Tibetan "blue sea". Located in the northeast of Qinghai-Tibet Plateau, Qinghai Province, China is the largest saltwater lake in China. In summer, Qinghai Lake has a bright sky, and the blue lake is as vast and magnificent as the sea. At this time, a large area of rapeseed blossoms blooming around Qinghai Lake, golden and yellow all over the land, and the distant Lake water, blue sky and white clouds cover each other, forming a colorful landscape painting. The sunrise and sunset of Qinghai Lake are very beautiful. Walking along the edge of Qinghai Lake, the mood is extremely pleasant.
