The document discusses the development of tourism in Shangri-La, Yunnan province, China. It examines the cultural, economic, social and environmental consequences of transforming Shangri-La into a major tourist destination branded after James Hilton's novel Lost Horizon. While tourism has boosted the local economy and preserved cultural traditions, it has also negatively impacted the environment, homogenized local culture, and benefited Han Chinese more than ethnic minorities. The future of Shangri-La tourism requires balancing economic growth with protecting the region's natural beauty and cultural authenticity.
