Single Dragon originates in Tibet; it flows through the northwest corner of Yunnan then into Burma. Its Yunnan section is 80 km long, clamped by mountains on both sides, Mt. Dandanlika on the west, Mt. Gaoligong on the east. There are 3 minorities, Dulong, Nu, Lisu, living in this area, they still keep very primitive folk customs, and many are still living on hunting and fishing. It's really an exciting adventure to trek into this remote and mysterious kingdom.
