Cao Gui's argument comes from Zuo Zhuan's Ten Years of Zhuang Gong. This paper narrates his comments on this war in the Battle of Long Spoon, and the historical fact that he used the principle of "gathering, losing and exhausting" to repel the powerful Qi army in wartime.
This paper expounds how to correctly apply the principle of strategic defense in the war-only by "winning the trust of the people", implementing the correct policy of "the enemy is exhausted and we will fight" and choosing the favorable opportunity for counterattack and pursuit can we strengthen with small enemies.
Extended data:
During the Spring and Autumn Period, Qi and Lu were neighbors, both in today's Shandong Province, Qi was in the northeast and Lu was in the southwest. In 697 BC, Qi Xianggong ascended the throne, and his decrees were impermanent. His younger brothers Xiao Bai and Gong Zijiu fled to Ju 'an and Lu 'an respectively. In the second year, Qi Xianggong was killed by Gongsun's ignorance. In the spring of the third year, the Qi people killed Sun Ignorant, and his son first returned to the State of Qi and proclaimed himself emperor.
Later, Duke Zhuang of Lu personally led the troops to escort the son back to China for a long time to compete for the throne. In August, Lu fought with Qi Shi, and the Lu army was defeated. Qi Huangong forced Duke Zhuang of Lu to kill Gong Zijiu. In the spring of the tenth year of Duke Zhuang of Lu, the State of Qi used the excuse that Lu had helped Gongsun Jiu to compete for the throne of Qi, and the two armies again confronted Lu. This is the battle of Qilu long spoon described in the article.
The battle between Qilu and Changshou described in this paper is a battle for Lu to resist the attack of Qi. Although it is not a big battle, it illustrates the principle of strategic defense, and it is a famous war example of defeating the strong with small enemies.
Mao Zedong said in the article "Strategic Issues of Revolutionary War in China": "During the Spring and Autumn Period, Lu fought with Qi. At first, Duke Zhuang of Lu wanted to go to war before Qi was exhausted. Later, it was stopped, and the strategy of "when the enemy was exhausted, we attacked" was adopted, and Qi was defeated, resulting in a famous war example in the history of China War.
The situation at that time was that the weak countries resisted the strong countries. This paper points out the political preparation before the war-winning the trust of the people; Describes the position that is conducive to counterattack-long spoon; It describes the time to start the counterattack-when I am exhausted and I am profitable; This paper describes the time when the pursuit began-when the flags were in chaos. Although it is a small battle, it is also the principle of strategic defense.
