The Long Songs of the Yue People

When the prince of Chu came back to his country, Xiong Lu fell ill in the palace. He went to the palace to inquire about his illness, saying that he had something secret to report, so he sent away his concubines, untied his tassels and put them on Xiong Mi's neck, and died in a moment... In the palace stables, Yin Xiong Heigong, whose character is Zixi, heard that the king of Chu and his son had been killed, and was afraid of disaster... Heigong ran away to Zheng... Then he succeeded to the throne, and was renamed Xiong Qian, who was the spiritual king... Wu Ju was left Yin. ―"The Chronicles of the Nations of the Eastern Zhou Dynasty·Chapter 67"
