Name

One of the earliest historical references to these mountains may be related to the Xiongnu word Qilian (traditional Chinese: 祁連; simplified Chinese: 祁连; pinyin: Qílián), which, according to Tang commentator Yan Shigu, is the Xiongnu word for "sky" or "heaven". Sima Qian, in the Records of the Grand Historian, mentioned Qilian in relation to the homeland of the Yuezhi, and the term is believed to refer to the Tian Shan rather than the range 1,500 kilometres (930 mi) further east now known as the Qilian Mountains. The name of the Tannu-Ola mountains in Tuva has the same meaning. The Chinese name Tian Shan is most likely a direct translation of the traditional Kyrgyz name for the mountains, Teñir Too.
