Qiu Chuji

Qiu Chuji (traditional Chinese: 丘處機; simplified Chinese: 丘处机; pinyin: Qiū Chǔjī; 1148 – 23 July 1227), also known by his Taoist name Changchun zi (Chinese: 長春子; pinyin: Chángchūnzi), was a Daoist disciple of Wang Chongyang. He was the most famous among the Seven True Daoists of the North. He was the founder of the Dragon Gate sect of Taoism attracting the largest following in the streams of traditions flowing from the sects of the disciples.

In 1219 Genghis Khan invited Changchun to visit him in a letter dated 15 May 1219 by present reckoning. Changchun left his home in Shandong in February 1220 and journeyed to Beijing. Learning that Genghis had gone West, he spent winter there. In February 1221, Changchun left, traversing eastern Mongolia to the camp of Genghis' youngest brother Otchigin near Lake Buyur in the upper Kerulen - today's Kherlen-Amur basin. From there he traveled southwestward up the Kerulen, crossing the Karakorum region in north-central Mongolia, and arrived at the Altai Mountains, probably passing near the present Uliastai. After traversing the Altai he visited Bishbalig - modern Ürümqi - and moved along the north side of the Tian Shan range to Lake Sutkol, today's Sairam, Almaliq (or Yining City), and the rich valley of the Ili.
