英语翻译麻烦把下面这段话翻译成英文,不要翻译器翻译一个民族的共同经济生活和表现于共同文化上的共同心理素质,都和本民族的穿

An ethnic groups's economy and performance, and the common psychology built on the foundation of a shared culture can all be related to their choice of ethnic costumes. In the study of ethnic identification and research, costumes are an important evidence that should be taken note of, and is undoubtedly an indispensable part of the research. Owing to different geographical, historical and social reasons, the world's different ethnic groups are greatly complicated. Not only are there many varieties, their origins are rather staggered as well. Therefore, to really sort out the clues to a ethnic group's development overtime and to ascertain the different circumstances of them, even to only name an ethnic group, is not an easy task. Costumes is an essential part of scientific research, it's role in indentifying the different ethnic groups and in related researched cannot be ignored. We can conclude that ethnic costumes is the best way for cultural heritage to be inherited. An ethnic group's quality of life depends on clothing, food and residence needs and materialistic needs. That their "First History Movement" is what contributes to the very foundation of their economy.
As of what kind of textiles are produced; what kind of clothing are sewn; what kind of jewelry are made, these will all depend on their production and craft skills. Also, we can see their advancement from their costume and jewelry.
