Five Hegemons
According to Sima Qian's "Records of the Grand Historian", Yuxiong, a descendant of the Yellow Emperor and his grandson Zhuanxu, was the teacher of King Wen of Zhou. After the Zhou overthrew the Shang Dynasty, King Cheng of Zhou (reigned 1042-1021 BC) awarded Yuxiong's great-grandson Xiong Yi the fiefdom of Chu, which over the ensuing centuries developed into a major kingdom. King Zhuang of Chu (reigned 613-591 BC) was one of the Five Hegemons, the most powerful monarchs during the Spring and Autumn period.
