In 2007, most residents were moved to nearby Jiayuguan City.[31] Some remote areas in China, such as Datong Hui and Tu Autonomous County (except Laoye Mountain), Huangzhong County (except Kumbum Monastery), and Huangyuan County around Xining, the capital of Qinghai Province, maintain travel restrictions for foreigners. A foreigner must apply for an alien travel document (外国人旅行证) in advance, and report their accommodation to local police within 24 hours after entering the area.[32] Similarly, all foreign visitors to the Tibet Area must be part of a tour group to be permitted access.
