In 1220, on the invitation of Genghis Khan with a golden tablet, Qiu Chuji left his hometown in Shandong with nineteen disciples, and traveled north through Beijing.
In June, they reached Dexing (德興; present-day Julu Hebei) and stayed in the Longyang Taoist Temple (龍陽觀) from summer to end of winter.
From there they went to Lake Buir, Hulunbuir, Ulan Bator, Arkhangai, Altay Mountains, Beshbalik, Dzungaria, Samarkand and arrived at Hindu Kush of Afghanistan in 1222 and presented himself before Genghis Khan.
