Xuzhou, Jiangsu
About Xuzhou, as far as I'm concerned, it has a strong cultural heritage, and although the city is not considered prosperous, it's not bad at all in China's prefectural administrative centers. In fact, good and bad, developed and backward are relative, I don't know where you come from, if you come from developed areas, such as Qingdao, Shenzhen, then I will tell you that Xuzhou is relatively backward, about the degree of openness, I don't know what your original intention is to ask this question, Xuzhou's degree of openness in general, Xuzhou is a national key industrial city and military strategic city, it is difficult to be liberalized by the central government. Referring to Zhangjiakou, the gateway to Beijing, the city's lagging development is evident. But in recent years Xuzhou's pace of development has accelerated, with the framework of a megacity gradually taking shape and the construction of a metropolitan area proceeding steadily. Of course, if you just come to study at the university, then the openness of Xuzhou should not constitute a direct impact on your studies, after all, China University of Mining and Technology is a 211 deployment of key universities, not subject to the jurisdiction of the municipal government of Xuzhou.
