The women's jewellery, and not least their milk hook, betray how near the Tibetan world is. The jewellery is decorated with corals and turquoises. At the same time, the pieces of jewellery clearly signal that they are worn by a Tebbu woman. Silver earrings are for the richer, copper earrings for poorer, or for everyday use.
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, and Tebbu Tibetans live mainly from livestock – yaks, horses, sheep and goats.
Further down, you find a Chinese population and Tebbu Tibetans that are farmers. The Drakana valley's population live in a transitional zone and combine agriculture down in the valley with animal husbandry up in the mountains. Culturally, they exist in the borderlands between Chinese and Tibetan culture, and this is observable in the artefacts from David Hummel's collection.
