The story of Gou Jian, King of Yue.

1 year, in 496 BC, He Lv, the king of Wu, sent troops to attack the State of Yue, and was defeated by the State of Yue. He Lv was also seriously injured and died. Two years later, He Lv's son, Fu Cha, led an army to defeat the state of Yue, and Gou Jian, the king of Yue, was escorted to the state of Wu as a slave. After serving the King of Yue in humiliation for three years, Fuxi cleared his guard and sent him back to Yue.

In fact, Gou Jian didn't give up revenge. On the surface, he obeyed the king of Wu, but secretly trained elite soldiers, strengthened the government, and waited for an opportunity to fight back against Wu.

3, hard work can exercise the will, but ease will kill the will. Gou Jian was afraid that he would covet the comfort in front of him and kill the will for revenge, so he arranged a hard living environment for himself. He doesn't need a mattress to sleep at night, just spread some firewood, and hang a gallbladder in the house. In order not to forget the shame of the past, he will taste the gallbladder from time to time. In order to inspire the people, Gou Jian, together with the Empress and the people, and with the help of Qi Xin, the Vietnamese, made the State of Yue strong and finally found the right time to destroy the State of Wu.
