Fan Si Mountains

The mountains south of the Red River form a rugged borderland of high ridges and deep valleys. In the Huanglian Mountains, the southern continuation of the Ailao range, moist monsoon forests cover steep slopes. Great differences in elevation produce a variety of climates and vegetation, from warm valleys to cooler uplands. Streams descend through the forest towards the river systems that cross the lands of the Hani and their neighbours.
