The river here refers to the Yellow River. Later, because the Yellow River flowed through the Loess Plateau, the water contained a large amount of sediment and the water color was still yellow, so it was named "Zhuo River". "Historical Records. "The Benji of Emperor Gaozu" records: "Fu Qi is bounded by Langya and Jimo in the east, solid by Mount Tai in the south, and bounded by the Zhuohe River in the west." It was not until the Eastern Han Dynasty that the name "Yellow River" came into being. It was first seen in Ban Gu's "Book of Han": "The oath of the title is to make the Yellow River like a belt and Mount Tai like a strong force." However, the common use of the name Yellow River began in the Song Dynasty, and was shortened to "Huang". For example, in "History of the Song Dynasty", there are sayings: "Huang, Bian, Qing, and Yu".
