We reviewed the concept of race and its development, analyzed the chaotic application of “race”, “ethnicity” and “ethnic group” at present, put forward the importance of distinguishing these concepts and put forward specific suggestions for distinguishing them. It was also pointed out that although the boundaries of race were blurred, the differences between races were narrowing, and the concept of race was fading, the concept of race can not be abolished. In practice, these concepts were used correctly according to context. At present, the concept of race was questioned, but whether the concept of race had a biological basis or not, it cannot be used as the reasons for racism.
