(Datong ancient city plan and streets of the Ming Dynasty) 
Today’s Datong’s ancient city basically keeps the road fabric from Ming Dynasty: city’s north, south, west and east main streets together compose the shape of character”十”, which divide the whole city into four areas. ] Then, whithin the sub-area, there are secondary streets to divide the area into smaller area. This kind of chessboard type street system is not unqiue in ancient chinese cities. Take Xi’an as an example, we can see the similarity between these two.
