What is the core content of "the dispute between China and Xia" in traditional culture?

First, "discrimination." That is to distinguish the differences between the Han nationality and the border ethnic minorities in economic model, living customs and cultural system, and admit the objective existence of the gap between them. From the above discussion on the origin and evolution of the concept of "Yi Xia", it can be seen that since the Spring and Autumn Period and the Warring States Period, the ethnic minorities in Sifang and the Han nationality in the Central Plains have generally lived in different environments, engaged in different occupations, and have their own lifestyles and customs, so they have actually been divided into two worlds, or even opposed to each other.

Second, we should attach importance to the objective economic and cultural differences between the two countries and recognize the differences in cultural values. The purpose is to judge the value and distinguish between advanced and backward, so as to have confidence in the superiority of Chinese culture, maintain its dominant position and make it an example for the study of "Four Foreigners".
