Formerly called Zhongdian County (中甸县; Zhōngdiàn Xiàn) but it was renamed on 17 December 2001 and upgraded into a county-level city on 16 December 2014 as Shangri-La (other spellings: Semkyi'nyida, Xianggelila, or Xamgyi'nyilha) after the fictional land of Shangri-La in the 1933 James Hilton novel Lost Horizon, in an effort to promote tourism in the area.
