The Battle of Aileen was a famous battle in which Lu and Wu defeated the Qi army in Aileen area in 484 BC. In the thirty-sixth year of the week, the allied forces of Wu and Lu defeated the Qi army in Ai (now the northeast of Laiwu, Shandong). In order to dominate the Central Plains, Wu joined forces with the armies of Lu, Yong and Yong to attack Qi in thirty-five years, and sent sailors to attack Qi from the sea, which was defeated by Qi. The following spring, the State of Qi attacked the State of Qi in retaliation for the warlords, and sent troops to attack the State of Lu, which was defeated by the army of Lu. In May, Fu Cha, the king of Wu, heard that the Qi army was attacking Lu, led Wu Jun to attack with Lu army, conquered Bo (now southeast of Tai 'an, Shandong Province), gained victory (now northwest of Laiwu, Shandong Province), and fought a decisive battle with the main force of Qi army in Yiling. "Zuo Zhuan" mourned for eleven years: "Because of the suburban war, the guild will cut Wuqi." That is, in the spring of 484 BC, Qi Jiangguoshu and Gao Wupi led their troops to the outskirts of Ludu and failed. Lu wanted to unite Wu Jun to cut Qi, so he persuaded Wu to cut Qi. At this time, in order to save the face of the failure of cutting Lu, the Qi army wanted to cut Lu again. Wu wants to dominate, and he wants to use the opportunity of Lu Lian Wu to attack Qiang Qi. Then, a fierce battle broke out-the battle of Aileen. "Zuo Zhuan" mourned the public for eleven years: Wu Wei "The Chinese army followed the king, the Xumen nest went up to the army, and the prince went down to the army, which shows that it is like the right army." Qi said, "Qi sent the credentials of Ai Cave to the Chinese army, while Gao joined the army, while Zong Lou joined the army." Each side rode thousands of cars, each claiming to be a hundred thousand troops. It also reads: "Bok in May, as for Ren Shen who won." "Jia Rong, the battle of Yiling. Exhibition is like defeating Xu's men's nest. The king's minions helped him and he defeated his troops. Those who have obtained the credentials are Gong and Lu Qiuming, and the first batch of 3,000 will be presented to the public. " The same is true of the records in the history of the Eastern Zhou Dynasty. In May, Wu Jun captured Bo, captured the city on May 27th, and entered Ailing (now Miaoshan Town) on May 29th. Macheng to Miaoshan is more than 20 kilometers, about 1 day, and Wu Jun can reach it in more than two days.
