the Ming rulers systematically rejected many of the Mongol policies and institutions. They expelled the Muslim, Christian, and Jewish traders whom the Mongols had encouraged to settle in China, and in a major blow to the commercial system of the Mongols, Ming authorities abolished the failing paper money entirely and returned to metal. They rejected the Tibetan Lamaist Buddhism that the Mongols had sponsored, and replaced it with traditional Taoist and Confucian thought and traditions.
