Lhasa, the ancient heart of Lamaism, is a sacred destination for many. Those residing in cities such as Beijing and Shanghai, who are tired of all the hustle and bustle, come to this pure land just to seek inner peace. Sitting against the spectacular Himalayan Mountains on the sparsely-populated Qinghai-Tibet Plateau, Lhasa is listed among the most livable cities with nearly zero pollution. /VCG Photo
