Tsering Yangjan, 27, is eight months pregnant and will give birth at a hospital near her new home. "There are many risks in having a baby at a high altitude. Being able to have a baby in a new home at a low altitude has made me less worried," she says.

Niangsang and the children form Guogencaqu village are chatting. His son will attend Semburi Kindergarten next year. "The wind rages all year round in Shuanghu.
