"The Kingdom of Daqin" section of the 5th-century "Book of the Later Han", which was largely based on Ban Yong's report presented to Emperor An of Han in around 125, lists precious Roman trade goods including "luminous jade [夜光璧]" and "bright moon pearls [明月珠]" (tr. Hill 2015 1: 25). He's jade-disk is occasionally (e.g., "Huainanzi" below) mentioned with the Xiahou clan's semi-circular jade pendant: Xiahoushi zhi huang (夏后氏之璜), which was a fabulous jewel supposedly included in the ducal regalia of Lu state (Major et al. 2010: 247). "Xiàhòu" (夏后) is a Chinese compound surname from the Spring and Autumn period (771-476 BCE), and the "huáng" (璜, "semi-circular jade pendant") was anciently used for ritual purposes or as a belt ornament. Tai'e or Tai'a (太阿) is the name of a famous Spring and Autumn period iron sword that is usually considered one of the ten legendary swords of China. The legendary bladesmith Ou Yezi made three swords for King Goujian (r. 496–465 BCE) of Yue, named "Tài'ē" (泰阿, Great Riverbank), "Lóngyuān" (龍渊, Dragon Gulf), and "Gōngbù" (工布, Artisanal Display) (tr. Milburn 2010: 285). The Chinese story of Mr. He's jade-disk has been repeatedly iterated for over two millennia. 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).
