General Secretary Xi Jinping attaches great importance to the issues of the times and analyzes the development direction of humankind from the perspective and method of Marxism. Further, he indicates that we must base ourselves on the overall strategy of the great rejuvenation of the Chinese nation and the significant changes occurring in the world that have not been seen in a century and makes a major judgment that the timing and international situation are favorable to China. Inevitably, Chinese now view themselves as equals of any other in the world, reflecting a historic change in the relations between China and the remaining world. In other words, no country can dictate terms to China. Building a powerful modern socialist country is a great goal set by the Communist Party of China(CPC). To build a great country and achieve a great cause, we must go through enormous struggle. Xi Jinping Thought on Diplomacy reflects on the issues of our times. Answering the questions and guiding the changes of our times, Xi Jinping Thought on Diplomacy is of great significance. Moreover, the CPC has remained true to socialism, and socialism has proved its worth to China.展开更多

However, this is not fact because some new concepts have been put forward in this paper where there is only a concept of infinitely great that is one quantitative continuum implied by the change of direction. The accurate description of this one quantitative continuum is that its parts are connected each other as a unity at the infinite distance (infinitely great) relative to any orientation (all orientations) of our existence. It is unity in which its random parts are these infinitely great quantities and thus we call this unity as infinite quantities of infinite dimensions.展开更多

It is worth while to note three new trends: the emergence of mega-urbanization regions; the rebuilding of a closer tie between the Chinese urban systemand the global one through the development of the global cities; and the polarized development in hinterlands and peripheries around advanced economic regions. However, the research literature onChinese urbanization in English has shown the scarcity of good databanks and the analysis results areincomplete. Using the most complete and latest data, this paper reviews the change of China’s designated cities before and after 1949. This paper also seeks to examine the various policies and explorethe underlying factors that have affected the growth of the new cities.展开更多
