Introduction to Namtso Lake: Namtso Lake is the second largest saltwater lake in China. Its Mongolian name is "Tenggri Sea", and both names mean "Sky Lake". It is said to be the dojo of Chakrasamvara, the deity of Tantric Buddhism, and is a famous holy place in Tibetan Buddhism. Every year, it attracts many believers to make a pilgrimage around the lake in order to seek the transcendence of the soul. The blue and pure lake water of Namtso, against the backdrop of the snow-capped mountains, makes people's whole soul seem to have been washed, and the feeling of praise still arises while the soul is shocked.
