摘要：Yuan Dynasty was an important period for Yunnan Province in history. The roads access to Huguang Province did not only promote the great development of the politics and economy of Yunnan Province, which actually surpassed any dynasty previous to it, but also strengthened the contacts with the inner parts of China, promoted the national amalgamation, and enhanced the centripetal force of Yunnan Province, finishing the situation of 500-year separation and leading the growth of Yunnan Province to a new stage.
