We returned to Lhasa for Yanghu and Tianhu Namco and stayed for another three nights. Fortunately, when we arrived at Namco, the rain stopped and the sun came out. Namcuo, the highest saltwater lake in the world, waited for us quietly under the blue sky and white clouds, like an emerald falling from the sky, the beauty was suffocating. This is a famous pilgrimage place of Tibetan Buddhism. The parking lot is about 1,000 meters away from the lake scenic spot and needs to walk there. There are many tourists in summer, and the sanitation around the scenic spot is not good. But Namco is a place that must come once in a lifetime.
