(1) The golden cicada escapes from its shell
During the opening year of the Song Dynasty, Jin soldiers repeatedly invaded the Central Plains. Song general Bi Zaiyu faced off against the Jin army and won several battles. The Jin soldiers mobilized tens of thousands of elite cavalry to fight the Song army decisively. At this time, the Song army only had a few thousand troops. If they fought a decisive battle with the Jin army, they would definitely lose. In order to preserve his strength, Bi Zaiyu prepared to retreat temporarily. The Jin army has already arrived at the city. If they know that the Song army is retreating, they will definitely pursue them. In that case, the Song army must have suffered heavy losses. Bi Zaiyu was thinking hard about how to deceive the Jin soldiers and move the troops. The pair only heard the sound of horse hooves outside the tent, and when they met again, they were inspired and took up their plans.
He secretly made retreat arrangements. At midnight that day, he ordered his soldiers to beat the war drums. When the Jin army heard the drums, they thought that the Song army had robbed the camp at night and hurriedly gathered their troops to prepare for the battle. Unexpectedly, I only heard the rumbling of war drums from the Song camp, but not a single Song soldier came out of the city. The Song army beat drums continuously, disturbing the Jin soldiers all night long. The leader of the Jin army seemed to have realized something: It turns out that the Song army adopted a strategy of exhausting the troops and used war drums to disturb our peace. Well, you beat your drum, I will never be fooled by you again. The drums of the Song camp rang continuously for two days and two nights, but the Jin soldiers ignored them at all. On the third day, the Jin soldiers discovered that the drum sound of the Song camp was gradually weakening. The leader of the Jin army concluded that the Song army was exhausted, so he sent troops to outflank the Song camp in several directions and cautiously approached the Song camp, but saw no response from the Song camp. The leader of the Jin army gave an order, and the Jin soldiers rushed forward and rushed into the Song camp. Only then did they find that the Song army had safely evacuated.
It turns out that Bi Zaiyu used the "golden cicada escapes from its shell" plan. He ordered the soldiers to tie the hind legs of dozens of sheep to trees and make the front legs of the hanging sheep kick as hard as they could. He also placed dozens of drums under the legs of the sheep. . Bi Zaiyu used the strategy of "hanging sheep and beating drums" to confuse the enemy and used two days to move safely.
(2) "Extensive but not refined"
The idiom "Extensive but not refined" means a metaphor for broad knowledge but not profound knowledge.
This idiom comes from "The Later Han Dynasty" "Book. Ma Rong Biography", Jia Jun is good but not knowledgeable, Zheng Jun is good but not good, even if he is good, he is also knowledgeable, how can I add more?
Zheng Xing, a famous Confucian scholar in the Eastern Han Dynasty, studied "Zuo Shi Chun Qiu" He is famous in the world. His son Zheng Zhong studied this classics work from his father when he was twelve years old. Later, Zheng Zhong also studied "Zhouyi", "Mao Shi", "Zhouli" and other classics works, which made him knowledgeable. He was knowledgeable, knew almost everything, and was very famous in the upper class.
After Zheng Zhong became an official, he explained classics such as "Mao Shi" and "Zhou Rites" to some young people in his spare time. He also spent a lot of energy on writing annotations for "Zuo Shi Chun Qiu". Later, he finally completed the annotation work for "Zuo Shi Chun Qiu" and the "Zuo Shi Chun Qiu" annotated by another classics scholar Jia Kui. " are both equally famous and highly praised by scholars. At that time, the most famous Confucian scholar was Ma Rong. He annotated "Zhouyi", "Shangshu", "Mao Shi", "Three Rites", "The Analects of Confucius" and "The Classic of Filial Piety". Ma Rong, in addition to annotating classics, also annotated "Laozi" and "Huainanzi". He sat in the high hall and hung a gauze curtain during his lectures. The students sit and listen to the lectures in the front, and a group of female musicians play music in the back, which is very unique.
After Ma Rong studied "Zuo Zhuan", he also prepared to write a "Zuo Shi Chun Qiu". After reading the annotations by Jia Kui and Zheng Zhong, he commented: "Jia Kui's annotation is profound but not extensive, while Zheng Zhong's annotation is extensive but not profound. If they are both profound and broad, how can I surpass them?" Ma Rong felt that these two annotations each had their own strengths, and together they made up for their respective shortcomings, so he decided not to give Zuo's Spring and Autumn Annals any more.
