Words describing wars, such as fighting with each other, the ancient battle of Kingoma Iron.

In the Battle of Julu in 206 BC, Xiang Yu burned his bridges and defeated Zhang Han. This war has two meanings: first, the main force of Qin Jun was eliminated, and the peasant army took the initiative in the war; Second, Xiang Yu jumped from a general to the commander-in-chief of the allied forces, and the war situation began to change from a battle to a Chu-Han war.

This idiom comes from Three Kingdoms, Biography of Shu Wei and Biography of Xun Yu.

At the end of the Eastern Han Dynasty, after Cao Cao suppressed the occupation of Yanzhou (Y m 4 n) by the Yellow Scarf Army, he was ambitiously preparing to seize Xuzhou.

At that time, there was a gifted scholar named Xun Xuan in Yingchuan, Angelababy (now Xuchang, Henan), who moved to Jizhou to escape Dong Zhuo's rebellion and was regarded as a distinguished guest by Yuan Shao. Seeing that Yuan Shao could not achieve great things, he went to Cao Cao's door. Cao Cao was overjoyed and named him Sima. From then on, he followed Cao Cao to the north and made suggestions, which won Cao Cao's trust.

In A.D. 194, Tao Qian, a shepherd in Xuzhou, died of illness and gave Xuzhou to Liu Bei before he died. When the news came, Cao Cao couldn't hold back the heart of Xuzhou any longer and was busy sending troops to Xuzhou. Knowing Cao Cao's thoughts, Xun Yu said, "When Emperor Gaozu was in Guanzhong, Emperor Guangwu Liu Xiu owned Hanoi. They all have a solid foundation. They advanced enough to defeat the enemy and retreated enough to hold on, so they became a great cause. Now the general is attacking Xuzhou regardless of Yanzhou, and it is not enough for our army to stay in Yanzhou to obtain Xuzhou; Stay less, if Lyu3 bu4 moves at this time, it will not be enough to hold Yanzhou. In the end, Yanzhou must have lost it, and Xuzhou didn't take it. " He also pointed out, "Now is the wheat harvest season. I heard that Xuzhou has organized manpower to grab wheat outside the city and transport it to the city. This shows that they are ready. Once the news comes out, they will definitely strengthen their fortifications, transfer all materials, and make all preparations to meet us (the original text is:' Today's wheat harvest in the East, it will be difficult for the generals to clear the field'). In this way, your military forces are really gone, the city can't be captured, and nothing can be obtained. Within ten days, your army will be defeated without fighting. "

Cao Cao listened to Xun Xuan and admired him very much. From then on, he concentrated his forces and quickly defeated Lu Bu. Later, he defeated Liu Bei and occupied Xuzhou.

"Fixing the wall to clear the field": Fixing the wall is to strengthen the city wall and fortress; Clearing the field is to collect food and property in the wild. It is untenable to reinforce fortifications and transfer all residents and materials in the four fields so that the enemy can neither break into houses nor take anything. This is a way to confront the superior enemy.
