Kublai Khan established his capital at Beijing and built a magnificent palace complex for himself, the Forbidden City. An architectural triumph, the Forbidden City contained elements of Arabic, Mongolian, western Asian, and Chinese architectural styles; it also contained a vast area of Mongolian nomadic tents and a playing field for Mongolian horsemanship. The Forbidden City of Kublai Khan, then, was in many ways a protected sanctuary of Mongolian culture. This aloofness from the Chinese exemplified by the Forbidden City was carried over into almost every other aspect of Mongolian rule. Although they adopted some aspects of Chinese culture, the Mongols pretty much refused to learn Chinese. The government, however, was run by Chinese officials selected under the civil service examination. Communication between the upper and lower reaches of government, then, was possible only through translators.
