Zhaxi Cairang (right), a 59-year-old Tibetan nomad, moved to a city in western China 15 years ago as part of a government effort to settle nomads. But Zhaxi says he plans to return to herding yaks next year. His son Cicheng Randing was raised in the city, but his father wants to expose him to traditional nomadic life as well. (NPR)
