Yak Museum a labor of love for curator

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 had to hide in a mud-brick house while the blizzard raged. Temperatures outside dropped to -30 C, and food was running out. Hope seemed to be fading away.

When the rescue team finally arrived with yaks carrying lifesaving supplies, Wu immediately bonded with the beasts.
