Why did Du Yu become one of the commanders in the Battle of Jin and Wu? What's his skill?

(1) Du Yu's life and knowledge

Du Yu (222 -285) was born in Ling Du, Jingzhao (now Xi, Shaanxi). Since childhood, I have been widely read and diligent in writing, and have studied military affairs, economy, politics, calendar, law, mathematics, history and engineering. The world appreciates his erudition, just as an arsenal has everything, and is called "Dooku".

He was a famous politician, strategist and scholar in the Western Jin Dynasty. He served as Cao, Henan Yin, Anxi Army Division, Secretariat, Shangshu and Zhennan General in the Western Jin Dynasty. After his death at the age of 63, General posthumous title Nan, Kaifu Instrument Co., Ltd. and posthumous title Chenghou.

He was the only one of the "two temples" (Confucian Temple and Wu Temple) before the Ming Dynasty.

(2) Du Yu has the military command ability to strategize and win thousands of miles.

In 265 AD, after the demise of Western Shu, Wei Emperor Cao Huan abdicated, and most of the world went to gold. Sima Yan officially proclaimed himself emperor, with a great title and a surname.

After more than ten years' development, in 277 AD, it was decided to attack the State of Wu in five ways with 200,000 troops, and Du Yu was appointed as the general of Zhennan, leading all the way and coordinating the other four ways.

As soon as Du Yu arrived, he arranged to repair the broken armor in the army. After the soldiers put on their perfect armor, they all looked mighty and their morale improved quickly. At the same time, he selected elite soldiers to form rangers, attacked the military camp of Zhang Zheng, commander-in-chief of the Western Mausoleum of Wu, and captured many prisoners.

Zhang Zheng was ashamed to report on the military situation. Du learned of this situation in advance, and immediately released all the prisoners in a deviant way. When the prisoners returned to China, the news was made public. Sun Hao, the prince of Wu, was very angry and ordered Liu Xian to succeed Zhang Zheng. A change of heart distracted Wu Jun, and his fighting capacity dropped sharply.

Du Yu seized this favorable opportunity and began to formally confront Wu. He arranged some troops in Jiangling, the gateway of the State of Wu, secretly sent Zhou Zhi, two generals of the State of Wu, to lead an army to raid Lexiang, and planted flags around to set off fireworks, disturbing the enemy's morale. Sun Xin, commander-in-chief of Wu Jun, was ambushed and captured in the battle. Many officers and men of the Jin army shouted happily: Take the plan instead of the war, and take one as ten thousand.

Du Yu immediately led the main force to attack Jiangling, and the general Yan Wu, the defending city of Wu, pretended to surrender. Du Yu discovered Yanwu's trick, quietly played along, occupied Jiangling in one fell swoop, and then all the way south, many states and counties of Wu surrendered.

At this time, the other four generals suggested that the rainy season is coming, the disease will be popular, and the attack will be suspended until winter. Du Yu urged people to do a good job of cooperation and led the army to continue the attack. Within three months, the State of Wu was destroyed.

According to the Book of Jin, Du can't even ride a horse. He is a real scholar, but the people of Wu hate him very much. To what extent? Didn't Du Yu have a big neck disease? They put all kinds of water scoops on the dog's neck, with a clear meaning, and compared Du Yu to a dog.

Why do Wu people hate him so much? The most direct reason is that the army he commanded killed or captured many senior officials of the State of Wu. In the Battle of Wu, Du Yu killed and captured 14 senior (provincial and ministerial) officials, such as the governor of Wu and the army governor, and as many as 120 middle-level (departmental) officials, such as chiefs and generals.

(3) Du Yu is an expert in economic development.

Shortly after Sima Yan ascended the base, Xiongnu Right Xianwang rebelled against Jin, and prepared to make a crusade, so that the ministers at that time (Du Zhi's ministers were equivalent to the ministers of the Ministry of Finance in the Ming and Qing Dynasties, and were in charge of the national finance) Du Yu drafted a conquest plan.

The next day, Du Yu gave Sima Yan a suggestion to resume production and construction as soon as possible.

Due to years of war, the country's financial resources are simply unable to undertake new wars. Although Sima Yan was a little unhappy, he summoned Du Yu alone to convince him. Du Yu seized the opportunity to analyze the pros and cons in detail. Sima Yan was impressed by his foresight, agreed to Du Yu's plan to give priority to economic development, and at the same time dismissed the idea of going to crusade against Liu Meng at once.

"Agriculture-oriented" is the traditional basic national policy of China. In order to further show the importance of agriculture, Du Yu suggested that Sima Yan should learn from Liu Heng, the emperor of China, and personally lead the royal family to cultivate their "homeland" every spring.

In order to transport military supplies in wartime, the imperial court and local governments raised many cows at that time. According to the Book of Jin, about 45,000 pigs were raised at that time. Du Yu suggested that during the busy farming season when there is no war, these idle livestock can be rented to cattle-free farmers at a suitable price, so that the country can not only get rent to increase its income, but also save a lot of money for buying feed.

In the history of China, harnessing rivers and water is an important work related to the national economy and people's livelihood. In view of the frequent floods in Jingzhou, Yangzhou, Yanzhou and Yuzhou, Du Yu put forward practical suggestions for water control to the court. After getting the approval, he personally made specific arrangements. After hard work, these places later became rich places with sharp changes in drought and flood.

Du Yu actively suggested making a blower that exhausts air by manpower, which was very advanced at that time and greatly promoted the ironmaking industry. After many experiments, it finally succeeded.

Du Yu suggested that the imperial court set up a standing warehouse, which can not only be used to reserve grain, but also stabilize food prices. In addition, Du Yu also suggested that all the rights to produce, transport and sell salt should be nationalized.

After the implementation of Du Yu's above-mentioned series of suggestions, it has effectively promoted social and economic development and increased national fiscal revenue.

(4) Du Yu has made great achievements in academic research. Later, according to his scattered opinions on strength and weakness, some experts compiled and compiled a wonderful book, Defending the Weakness.

Du Yu is knowledgeable and versatile. He calls himself "Zuo Zhuan" and his works are handed down from generation to generation, such as Chunqiu Jingzhuan, Chunqiu Tu, Chunqiu Changli and Nuwa Sacrifice.

Mr. Ma Shuquan, an expert in the collation of modern ancient books, compiled the book "The Study of Defending the Weakness" according to Du Yu's "On the Potential of the Strong and the Weak".

The main reason discussed in Defending the Weak is the principle that the strong will be strong and the weak will be weak. But weakness and strength are not immutable. A person's life is sometimes in a strong position and sometimes in a weak position. The function of weakness is to "keep the strong weak and make the strong strong;" The weak are the weak, and can change from weak to strong. "

There are nine volumes in the book, and every sentence is classic.

Such as "wisdom": the original text is: wisdom is wisdom, and wisdom is not good. It means: a wise man takes wisdom as the way to win, and if he uses it improperly, it will backfire.

The author tries to make an analysis: there is no perfect wisdom in the world, and even the most brilliant wise men sometimes miscalculate. Smart people should understand that many things cannot be won. If a wise man bears a heavy burden of victory, once he encounters setbacks, it will directly lead to his failure. We must understand the truth that there is someone behind us one day. If the mentality is wrong and the mind is fragile, the fate of the wise is not good after all.

As the saying goes, "fool": the original text is: a fool is better than a fool, and if there are too many fools, they will be caught. It means that a fool takes his own stupidity as the way to win, even if his head is full of stupidity, he can achieve his goal.

People are most likely to overlook the positive role of stupidity. Many people just want to be slick, and as a result, they draw tigers instead of dogs. No matter whether it is a white cat or a black cat, it is a good cat that can catch mice. As long as you achieve your goal, you won't be stupid.

Many successful people in history are not only not smart, on the contrary, they are very stupid. It is precisely because he knows that he is stupid, does things without opportunism, and is tough and solid that he successfully started a career that is difficult for smart people to complete. From a certain point of view, success requires a kind of "stupidity" with no distractions.

Du Yu's theory of "defending the weak" is inseparable from his successful practice all his life. It goes without saying that "defensiveness" is a very practical university question. It is said that "Research on Defensive Weakness" is a wonderful book from ancient times to the present, and once you learn it, you will benefit for life.
