Event background: King Xiang of Song wanted to dominate the vassal and become an ally. The state of Chu is powerful, and the vassal of Zheng recommended it, and the state of Chu became the leader. King Xiang of Song was indignant and angered Zheng. The Chu army attacked Song State to rescue Zheng State. When Song Xianggong was ready to fight, Fu Sima Ziyu dissuaded him and said, "God has abandoned Shang Dynasty for a long time, and it is unforgivable for the king to revitalize it." Xianggong didn't listen. Xiang Gong led the troops to fight with the Chu army at Hongshui. Song Jun has lined up, but ChuJun hasn't completely crossed the river. Zi Yu said, "There are many of them and few of us. Please give an order to attack them before they all cross the river." Xianggong said, "No." All the Chu troops crossed the river, but before they lined up, Ziyu reported the above opinions to Xianggong. Xianggong said, "Not yet." Wait until ChuJun lined up, and then attack them, as a result, Song Jun was defeated. Song Xianggong was injured in the leg and all the guards were killed. The whole country is guilty of helping the public. Xiang Gong said, "A gentleman will no longer hurt people who have been injured or capture people with gray hair. In ancient times, the principle of leading troops to fight was not to stop the enemy by virtue of the narrow terrain. Even if I am a descendant of the Yin Shang who died in the country, I will not attack the troops that have not been lined up. " Zi Yu said, "You don't know how to fight. The strong enemy's army can't line up in a dangerous place. This is God's help. Isn't it possible to stop the enemy from attacking them in dangerous places? (That's it) Are you afraid you can't win? And now we face the strong, are our enemies. Even very old people, if they are captured, they will be captured. What do you care about gray hair? Shame is used to boost soldiers' morale and teach them combat skills in order to kill the enemy. You haven't hurt (the enemy) to death. How can you not hurt them again? If you pity (them, don't want to) hurt the injured enemy again, you should start not hurting them; If you pity the gray-haired among them, you might as well give in to the enemy. The army should seize the fighter plane to attack, and the bells and drums use sound to improve morale. It is possible to attack when the opportunity is favorable and stop the enemy in danger. Drums are loud to boost morale, and it is also possible to attack enemies who are not in line. "
