Since Fu Chai got Xi Shi, he has been living in Gusu Terrace, enjoying himself and playing all year round, and no longer cares about political affairs. The ministers in the court who had advice were either reprimanded, expelled, or dismissed from office, so gradually everyone did not dare to speak out. Only the veteran minister Wu Zixu saw that King Wu was so unethical, so he remonstrated and dissuaded him in front of the Gusu stage, but King Wu still ignored him. Wu Zixu felt that the king of Wu was bound to bring disaster in this way, but he refused to listen to his advice, so he said he was ill and stopped going to court.
At that time, under Gou Jian's governance and rectification, the country's national strength was increasing day by day, and its army was well-trained. King Wu Fu Chai felt threatened and wanted to conquer Yue, but was blocked by Dr. Bo Shao's clever words.
Later, the relationship between Qi and Wu deteriorated, and Fucha wanted to attack Qi. Wu Zixu believed that the Yue State was a serious concern and it was not appropriate to conduct an expedition against the Qi State. However, Dr. Bo Shao insisted on attacking Qi State and guaranteed victory upon departure.
Doctor Bo Shao, who had always been in conflict with Wu Zixu, ignored the safety of the country and took the opportunity to provoke a conflict between the King of Wu and Wu Zixu. As a result, the King of Wu ordered Wu Zixu to die, promoted Bo Dafu to the position of Prime Minister, and also wanted to add fiefs to the Yue Kingdom, but Gou Jian refused. As later generations said: "The death of Wu should be blamed on the foolish emperor Fucha and the treacherous doctor Boshao."
In the early summer of 482 BC, the Yue Kingdom conquered Wu and won a great victory
