The Drakana Valley's population live in a transitional zone and combine agriculture down in the valley with animal husbandry up in the mountains. The great forests of the Tebbu Tibetan's valleys gave the raw material for amazing wooden houses.
They made wooden tools for working in the fields, and different types of container for storing and transporting food-stuffs in. Up in the mountains they milked the cross-breed of yaks and cows (dzo), which gave the fattiest milk. It was churned into butter that was sewn into sheep stomachs to be stored for cooking and preparing butter tea with. The butter was also delivered to all the monasteries' butter lamps.
The Tebbu Tibetans live in the long valleys north and south of the Yangtze River's northernmost tributary, Bailong Jiang. In the north, the over 5,000 meter-high peaks of the Min Shan Mountains separate their wooded valleys from the almost treeless landscape of the Yellow River.
At the top of the Bailong Jiang valley, you are close to the Tibetan highlands. Tebbu Tibetans live mainly from livestock – yaks, horses, sheep and goats. Further down, you find a Chinese population and Tebbu Tibetans that are farmers.
