Brief introduction of Yixian

The concepts of "Yi Xia" and "Yi" originally refer to the minority countries around China, and later refer to foreign countries. This has the meaning of respecting the outside world. The ancients in China thought that they lived in the middle of the turtle's back, while other countries said that Dieiman lived in the wilderness on the edge of the turtle's shell. The theoretical basis is the infinite soil with the theory of five elements as the core. Summer, Huaxia, refers to China. It was after the establishment of the Han cultural circle by Emperor Wu of the Han Dynasty that other nationalities learned from the Han nationality (including Korea, Japan and Southeast Asian countries). After the demise of the Ming Dynasty, the title Chongzhen was used in North China for hundreds of years, which shows how much it was influenced by Korean culture, so it developed a sense of superiority and called itself China. Discrimination against other ethnic groups is the concept of "Yi Xia".
