郑州在古代即为政治和军事的绾毂冲要之地,经济与文化的发达繁盛之区,史籍有载,遗迹可寻。唐宋以来,由于经济文化重心倾向于东南,而政治军事的热点则偏离于西北,使中原地区有时成为雄杰者逐鹿的场所,夺取统治权利的襟要;兵火之馀,呈现出一片荒原。以致治史者每侧重地缘经济的发展走向,而轻遗中枢地带所起的历史均衡作用。重偏侧则不足以概全,轻寰中则无能以制要,是故治史者贵乎胸有全局,主要就在这里。 In ancient times, Zhengzhou was the climax of political and military hubs, the flourishing area of ​​economy and culture, with historical records and traces of heritage. Since Tang and Song dynasties, the center of economic and cultural tendencies tend to the southeast, while the political and military hot spots deviate from the northwest, making the Central Plains sometimes become the place where the male players compete for each other to seize the dominant position of the ruling power. So that the history of each focus on geo-economic development, and the light of the historical balance of the central role. Rebalanced side is not enough to complete, light atheism is incompetent to make, so the history of governance is almost the chest, the main is here.
