During the Spring and Autumn Period, if he wanted to expand his power and territory, he made an excuse to say that Guo, a neighboring country, often violated the border of Jin and wanted to send troops to destroy Jin. But there is a dangerous country between Jin and Guo, and the crusade against Guo must go through dangerous places. "How can we successfully pass through the country of Yu?" Jin Xiangong asked his ministers. Doctor Xun said: "Yu's monarch is short-sighted, greedy and cheap." As long as we send him priceless jade and BMW, he will not refuse to borrow. " Jin Xiangong is a little unwilling to listen. Xun read his mind and said, "The two countries are close neighbors. Guo zhiguo is destroyed, and he can't be immune to it. Your beautiful BMW is only temporarily stored in Gong Yu. " Adopted Xun's plan.

Yu Guojun was very happy when he saw these two precious gifts. When Xun heard that he wanted to borrow something from him, he readily agreed. When Dr. Yu Guo heard this, he quickly stopped him and said, "No, no, Yu Guo and Guo Guo are close neighbors. Our two small countries are interdependent and can help each other if something happens. If the state of Guo perishes, our state of Yu will be hard to protect. As the saying goes:' the lips die and the teeth are cold', without lips, the teeth can't be kept! Never lend money to the state of Jin. " Qi Huangong said, "Jin is a big country, and now they specially send beautiful jade BMW to make friends with us. Can't we borrow a way to let them go? " Gong sighed again and again, knowing that the country of Yu was not far from the day of extinction, so he left the country with his family.

Sure enough, the army of the State of Jin rode the east wind of the State of Jin, destroyed the State of Guo, and then seized Qi Huangong, whom the State of Jin personally greeted, and destroyed the State of Jin. The story comes from Zuo Zhuan Xi Gong Five Years. The idiom "the lips are dead and the teeth are cold" means that the two sides are closely related and interdependent.
