We had a rare opportunity to see the wild Przewalski's horses up-close while travelling along 216 highway.

Xinjiang was the original habitat of the Xinjiang wild horse 60 million years ago. The wild horse is even rarer than the giant panda, as there are fewer than 1,000 in the world. Most live in zoos in Germany, Britain, the United States, the Netherlands and China. There are 200 wild horses in China at the most. "
