At the intersection of Chongqing north road and Nanjing west road, there erects a very special building. In stead of the usual shape of square, this building is a rounded circle. We call it Jiancheng Circle. It’s a place full of history and renovated into the modern appearance. Near the Circle, there are many food stores selling wonderful traditional gourmets. The food there is extraordinary just like the history there. Before we start eating, please take some time to learn some knowledge about this place with us.
