英文摘要：

Since the 18th congress of the CPC, comrade Xi Jinping has repeatedly stressed the importance of keeping in mind the basic national condition that China is a unified and multi - ethnic country, as well as that of cultivating the consciousness of the Chinese community. This indicates the direction of the development of ethnic work in the new period. The Chinese nation takes on the pattern of diversity in unity of the Chinese community in terms of ethnic structure, and has long preserved the political tradition of a muti - ethnic unified nation. It is indispensable to have a deep understanding and grasp of this situation and its far - reaching influence on ethnic work from the perspective of history combined with reality. It will contribute to the settlement of ethnic problems in the process of the ＂two hundred years＂ strategy, and supply strong national unity security and development motive for the great rejuvenation of the Chinese nation.
