is known as the “air way door” to Tibet, as well as the Shannan Lhünzê Airport in Lhünzê County. The Lhasa airport has direct air links with Beijing, Chengdu, Shanghai, Guangzhou, Chongqing, Xi'an, and Kunming. In addition, there are also international flights to Kathmandu and Hong Kong. It is from Lhasa. Regular buses operate from the two cities of Tsetang and Lhasa every day to the airport. From the time Tibet Autonomous Region has been opened for other countries, development of many infrastructure and social sectors have recorded dramatic progress such as education, telecommunications and tourism. The posts and telecommunications facilities first established in 1956 have now optical fiber link between Zetang and Lhasa. As a result, program-controlled telephones, personal pagers, mobile telephones and other modern communication facilities are linked with the national network. Zetang also has landlines, microwave and satellite communications and postal delivery vehicles. References Further reading Buckley, Michael and Strauss, Robert. Tibet: a travel survival kit.
