In 743BC he became the duke in Chang and later defeated his brother Gongshu Duan who led a rebellion against him. He was appointed Left Advisor by King Ping of Zhou. After King Ping’s death, the following king (King Huan) recalled him off official. In return for this, Duke Zhuang refused to go to the capital and meet King Huan. King Huan made a war against him. In this war he defeated the army of the king and hurt King Huan on the shoulder.
