Yak Museum gives curator lots to talk about

A part of Tibetan life for centuries, the revered animals provide food, clothing, labor and transport.

Over 40 years ago, Wu Yuchu was trapped in a blizzard in the Tibet autonomous region.

It was 1977, two years after Wu had started working in Tibet. He and more than 50 other people took shelter in a mud-brick house while the blizzard raged. The outside temperature dropped to-30 C, and food was running out.
