“不怕刀兵之险,就怕鱼鳖一患”。以“战争之城”著称的徐州自汉至清咸丰十五年的漫长岁月里,黄河流经徐州。历史上的黄淮水患让徐州成了典型的叠城,仅明代的城池就前后两座叠埋于流沙之下,这不仅使徐州城下的古文明积淀异常丰厚,也造就了徐州特有的文化现象——高地文明圈。 “Afraid of knife and knife risks, afraid of fish and turtle suffering.” Xuzhou, famous for its “City of War,” runs through Xuzhou from the Han to Qing Xianfeng for fifteen years. The Huanghuai flood in history makes the city of Xuzhou become a typical overlying city. Only the city of Ming dynasty was buried under two quicksands before and after. This not only made the ancient civilization under the city of Xuzhou extremely rich, but also created the unique cultural phenomenon of Xuzhou High civilization circle.
