During the Warring States period, princes disputed. In the Warring States Policy, we talked about the strength of Qi. Please read the fourth paragraph. In my own words.

Qin Xing wanted to be the master of the Zhou Dynasty, and Zhou Jun suffered greatly, in order to save face. Yan said, "Your Majesty, don't worry. I asked Dong to save Qi. " Yan led his troops to the State of Qi, and said to the King of Qi, "Zhou relied on the righteousness of a great country and was protected by his father and son, and he was willing to sacrifice his strength. I don't know how to be a big country to do it? " King Qi said, "I'll take you to see Liang." Yan rate said, "No, Fu Cha's monarch and his subjects must seek the glory under the stage and above the sea. After a long time, they will never get out when they enter the beam. " Yan said, "It is Wang Ye who suffers from stealing the city. Married people have no effect on their ears, but those who have no effect on their ears can be whipped or even brought together. Invalid birds gather to fly, rabbits let horses die, and ideas stop at people together. Last week, when Yin was cut, it won the battle. Each tripod is held by 90,000 people, and 99.81 million people are apprentices, so the compilers call it this. Today, even if the king has a man, how can he come out? I am secretly worried about the king. " King Qi said, "The number of children coming is still beyond our ears." Yan rate said: "I dare not bully the big country, but I will decide where to go, and I will move the tripod." Wang Qi is the only one.

Enemy at the Gates threatened the Eastern Zhou Dynasty and demanded Jiuding (a national treasure) from it. Zhou Jun was worried about this, so he discussed countermeasures with Yan, an important official in the DPRK. Yan said, "Your Majesty doesn't have to worry, but I can go east to Qi to borrow soldiers to help." Yan led his troops to the state of Qi and said to the king of Qi, "Now the king of Qin is cruel and heartless, and Enemy at the Gates, the master of violence, threatened Zhou Jun to take the position of the dominant position. During the Eastern Zhou Dynasty, I was thinking about countermeasures in the imperial court. Finally, ministers agreed that it was better to give Jiuding to your country than Bao Qin. Saving the country facing peril will make it famous and win the recognition and praise of the world; If you can get a national treasure like Jiuding, it is indeed a great blessing for the country. I hope the king can fight for it! " Hearing this, the King of Qi was very happy. He immediately dispatched 50,000 troops and appointed Chen as the commander-in-chief to save the Eastern Zhou Dynasty. Qin Bing really retreated. When the King of Qi was ready to beg for loyalty from Zhou Jun, Zhou Jun was in a hurry again. Yan said, "Your Majesty, don't worry. Please allow me to go to Qi to solve this matter. " Yan led a delegation to the State of Qi and said to the King of Qi, "I relied on your kindness to keep my father and son safe this time in the Eastern Zhou Dynasty, so I willingly gave Jiuding to the King of Qi, but I wonder which way your country will take to transport Jiuding back to the State of Qi?" King Qi said, "I want to borrow the beam." Yan said, "You can't borrow it, because Liang and his ministers have long wanted Jiuding. They have been planning this in Huitai and Shaohai for a long time. Therefore, once Jiuding enters the beam, it is difficult to come out again. " So the king of Qi said, "Then I'll borrow Chu." Yan rate replied: "This is no good either, because in order to get Jiuding, the monarch and ministers of the State of Chu planned for (the local name) long ago. If Jiuding enters Chu, it will never be shipped out again. " The king of Qi said, "Then where did I transport Jiuding to Qi?" Yan said, "I am personally worried about the monarch of the Eastern Zhou Dynasty. Because the so-called Jiuding is not something like a vinegar bottle or a sauce jar, you can get angry when you hold it in your hand or in your arms, unlike birds gathering, crows flying away, rabbits running and jumping, and horses galloping. After cutting Yin to win Jiuding, it used 90,000 people to pull the tripod, and Jiuding was 810,000 people. Soldiers and craftsmen need countless things, in addition to preparing corresponding handling tools and clothing and other materials. Now, even with such manpower and material resources, the king doesn't know which way to transport Jiuding to Qi. Therefore, I have been worried about the king in private. " King Qi said, "Xian Qing has come to our country many times, but he still won't give Jiuding to me after all!" Yan rate quickly explained, "how dare I cheat your country? As long as your majesty can decide which way to carry it quickly, my princes and ministers in the Eastern Zhou Dynasty can move around and wait for orders. " The King of Qi finally gave up the idea of obtaining Jiuding.
