In the Yuan Dynasty, Kublai Khan entered the Central Plains, and the Eight White Room moved to the capital, Khanbaliq. In the 1750s, Mandulu Khan led the Ordos Department into the area south of the Yellow River. Eight white rooms moved to Ordos. Soon, the son of Mandulu Khan came to dominate the grasslands, betrayed the golden family of Genghis Khan, and controlled the eight white rooms in their hands. Until the beginning of the sixteenth century, Genghis Khan's fifteenth generation of Sun Batu Mengke unified Mongolian ministries, and the eight white rooms were re-owned in the Genghis Khan gold family.
