Count the Yan state

King Hui of Qin married the princess to the prince. In the same year, Yan died of illness and Yan Wangyi acceded to the throne. After Wang Gang ascended the throne, Qi Xuanwang took the opportunity to send out an obituary to attack Yan State and occupy ten cities. ? King Iraq asked Su Qin to recover occupied territory for Yan. ?

When Su Qin arrived in the State of Qi, he went to visit the King of Qi, congratulating him first and then mourning. The king of Qi was puzzled and asked why. Su Qin said, "No matter how hungry people are, they will not eat poisonous black beaks. The more they eat, the faster they die. Yan State and Qin State are married countries. The occupation of Yan State by Qi State is tantamount to making enemies with Qiang Qin and being hungry. Qi is about to face extinction. " ? The King of Qi was frightened and asked him how to solve the crisis. Su Qin suggested returning the captured city, so that the prince would like it, and the king of Qin would be happy, so that he could turn disaster into joy. ?

The King of Qi thought that Su Qin was right, so he returned the occupied city of Yan.

Su Qin didn't cost a single soldier to lift the war and recapture ten cities, which is a word.
