The earliest extant account is the "Heshi" (和氏, "Mr. He") chapter of the c. 3rd-century BCE Legalist classic "Hanfeizi", attributed to Han Fei (c. 280-233 BCE). The "Hanfeizi" version involves Mr. He presenting his jade to the first three "kings" of Chu state: "King Li of Chu" (楚厲王) posthumously refers to Viscount Fenmao (r. 757-741 BCE), his brother King Wu of Chu (楚武王, r. 740-690 BCE) who was the first to style himself "king", and his son King Wen of Chu (楚文王, r. 689-677 BCE). Several "Hanfeizi" commentaries say these three 8th-century BCE Chu rulers of Pian He should be three 11th-century BCE Zhou dynasty rulers: King Wu of Zhou (周武王, r. c. 1050-1043 BCE) who founded the Zhou dynasty, his father King Wen of Zhou (周文王, r. 1100–1050), and King Cheng of Zhou (周成王, r. 1042-1021 BCE). The posthumous names for princes and kings of many dynasties after the Chu imitated these famous Zhou royal names Wu (武, "Martial; Military; Valiant") and Wen (文, "Cultured; Civilizing")—"wén-wǔ" (文武, means "civil and military").
