Shangri-La was formerly called Zhongdian County, but was renamed on 17 December 2001 and upgraded into a county-level city on 16 December 2014 as Shangri-La after the fictional land of Shangri-La in the 1933 James Hilton novel Lost Horizon, in an effort to promote tourism in the area. The Tibetan population refers to this place by its traditional name Gyalthang or Gyaitang, meaning “Royal plains”.
