The Central Plains is a very important concept in the history of China, and its scope has changed greatly since ancient times. The word "Central Plains" has been used in spoken language by people at that time as early as the Spring and Autumn Period, but it originally meant "Plain" or "Yuan Ye". For example, "The Book of Songs Xiaoya Jiri" says: "Looking at the Central Plains, there are holes."
