In 1264, Kublai Khan visited the Daning Palace on Jade Island in Taiye Lake and was so enchanted with the site that he directed his capital to be constructed around the garden. The chief architect and planner of the capital was Liu Bingzhong, who also served as supervisor of its construction. His student Guo Shoujing and the Muslim Ikhtiyar al-Din were also involved.
