编写这样一部书是非常有意义的。在漫长的历史进程中,我国56个民族相互依存、水乳交融、休戚与共,形成了中华民族多元一体的格局,共同推动了国家发展和社会进步。各民族无论起源早晚,人口多少,经济社会发展程度高低,风俗习惯和宗教信仰异同,都是中华民族大家庭中平等的一员。各 It is very meaningful to write such a book. In the long course of history, the 56 ethnic groups in our country are interdependent and integrated with each other and live together in solidarity. This has formed a pattern of pluralistic integration of the Chinese nation and jointly promoted the development of the country and social progress. No matter what the origin, population, level of economic and social development, customs and religious beliefs, ethnic groups are all equal members of the Chinese nation. each
