King Wu
Wu Geng or Wugeng (Chinese: "Wǔgēng") was an ancient Chinese noble who was the son of Zhou, the last king of the Shang. After his father executed Bigan by cutting out his heart, Wugeng fled to Feng, the capital of the Zhou state, together with his uncles Weizi and Weizhong to plead King Wu of Zhou for help. Shortly afterward King Wu attacked the Shang and defeated King Zhou at the Battle of Muye, thus establishing the Zhou dynasty. Wugeng was allowed to stay in Yin, the old Shang capital, and rule it as a princedom and a vassal lord to King Wu.
