禹貢
Pre-Qin dynasty (221 BC–206 BC) historical texts such as the "Yu Gong" or "Tribute of Yu" chapter of the "Book of History", "Erya", "Rites of Zhou" and "Lüshi Chunqiu" all refer to the Nine Provinces. Yuzhou appears in all of these texts even though different names are provided for the Nine Provinces. The "Rites of Zhou" states that Yuzhou was Henan Province, while the "Lüshi Chunqiu" records: "Yuzhou was between the Yellow and Han rivers. That was where Zhou was located."
