Introduction to the Military and Civilian General Administration Office: In 1328 AD, Emperor Wenzong of the Yuan Dynasty established the Military and Civilian General Administration Office on Yao'an Road next to Gao's Tuyamen. During the reign of Emperor Taizu of the Ming Dynasty, he was the general manager of the military and civilian affairs of Yao'an. The General Manager's Mansion sits in the west and faces east. Along the central axis are the Yimen, which are the places where guests are welcomed and sent off.
