The videos I watched became popular in ancient times

Du Yu came from a famous aristocratic family in Jingzhao. His grandfather Du Ji was the Minister of the Secretariat of Wei.

His father, Du Shu, was the governor of Youzhou.

Du Yu was knowledgeable and well-versed in the ways of a country's rise and fall. He often said that although he could not establish virtue, he could still establish merit and make statements.

In the first year of Jiaping, Sima Yi launched the Gaopingling Incident, completely defeated the Cao family group headed by Cao Shuang, and completely grasped the actual power of the Cao Wei government.

Du Yu's father was at odds with Sima Yi, and was exiled and died in prison after the Gaopingling Incident, so Du Yu was not able to be used for a long time.

"After Sima Yi and his son Sima Shi died of illness one after another, Sima Zhao took over the position of his father and brother and governed in the second year of Zhengyuan."

"Du Yu married Sima Zhao's sister Princess Gaolu as his wife, and was appointed as a minister of the imperial court, inheriting his grandfather's title of Marquis of Fengle Ting."

"Four years after Du Yu took office, Sima Zhao became prime minister, and Du Yu was transferred to assist the prime minister in military affairs."

"In May of the fourth year of Jingyuan, the Wei army divided into three groups to attack Shu. Du Yu was appointed as the chief officer of Zhong Hui's Zhenxi General's Office."

"After Wei conquered Shu, Zhong Hui rebelled and all his subordinates were killed. Du Yu escaped the disaster by virtue of his wisdom and was later granted an additional 1,150 households."

"In July 264 AD, Sima Zhao commissioned Xun Xu, Jia Chong, Pei Xiu, Zheng Chong and others to reform the etiquette, laws and official system."

"Among them, General Jia Chong and others were responsible for formulating laws and decrees, and Du Yu was also ordered to participate in this work and was the main annotator of the Jin Code."

"On the 12th day of the 12th month of the second year of the Xianxi reign, Sima Yan forced Cao Huan, the first emperor of Wei, to abdicate and ascended the throne as emperor. He named the country Jin and changed the era name to Taishi."

"Du Yu became a minister of the Jin Dynasty and served as the governor of Henan during the middle period of the Taishi period."

"After the revision of the law was completed, Du Yu submitted a memorial stating that the law is a criterion and model for judging cases, not a book that explores the principles of things and human nature in detail, so the text is concise and the examples are clear, and what is allowed and prohibited is concise and brief."

"The emperor issued an edict to promulgate this law and its annotations to the whole country."

"The person who nominally presided over the revision of the Jin Code was Jia Chong, and all the annotations of the Jin Code were completed by Du Yu."

"When Du Yu was the governor of Henan, he believed that the capital was the base for educating the world, and that from the nearest to the farthest, all his policies and writings must be based on the national policies."

"Du Yu was ordered to formulate the assessment regulations for the promotion, demotion, reward and punishment of officials, reaffirming the old system of Tang Yao, removing complexity and simplifying it, so that it is simple and easy to implement."

"He believed that if we follow nature, things in the world will fall into place."

"To assess and recommend the best and the worst, we must appoint knowledgeable officials to assess the officials in their respective areas."

"After one year in office, one person with outstanding performance will be selected as the upper grade, and one person with inferior performance will be selected as the lower grade. The statistics will be reported to the court."

"Use six years as a benchmark for promotion and demotion of officials. However, Du Yu's suggestion was not accepted by the court."

"In early 270 AD, Shi Jian, the lieutenant of the imperial court, impeached Du Yu because of a long-standing grudge against him. Du Yu was dismissed from his post."

"In June of the sixth year of the Taishi reign, the barbarians invaded the Longyou area. The emperor appointed Du Yu as the commander of the Anxi Army and gave him 300 soldiers and 100 horses."

"When he arrived in Chang'an, he was given the titles of Governor of Qinzhou, Commander of the Eastern Qiang, General of Light Cavalry, and Acting General."

"At that time, the Hulu army was strong, and Shi Jian was the General of Anxi, and he ordered Du Yu to lead troops to attack the Hulu."

"Du Yu believed that the barbarians had won the battle and their horses were strong, while the government troops were isolated and exhausted, so they should accumulate strength and wait for the right time to attack in the spring, so he stated five things that should not be done and four things that should not be done."

"Shi Jian was furious and reported to the emperor that Du Yu had renovated the city gates and official residences without permission, which had caused fatigue to the army. He sent the imperial censor to take Du Yu to the court in a prisoner cart."

"Because Du Yu's wife was a princess, she met the eight conditions for commutation of sentence in the criminal law, and was sentenced to redeem her crime by becoming a marquis."

"Later, the military situation in Longyou was exactly as Du Yu had analyzed and planned. At that time, everyone in the court believed that Du Yu had the talent to plan strategies."

"In November of the seventh year of Taishi, the Xiongnu commander Liu Meng rebelled against the Jin Dynasty and occupied the western part of Bingzhou, Hedong and Pingyang. The emperor issued an edict to let Du Yu make suggestions in the palace as a Sanhou, and soon he was appointed as the Minister of Revenue."

Li Bai: During the period when Du Yu was the Minister of Revenue, Shi Jian returned to the capital from the army and reported false achievements, which was impeached by Du Yu. The two of them then hated each other and were both dismissed from office.

Du Yu continued to hold his original position as a marquis, and was appointed Minister of Revenue a few years later.

From then until the fourth year of Xianning, Du Yu served as the Minister of Revenue for a total of seven years, and made countless suggestions.

During his tenure as Minister of Revenue, Du Yu submitted memorials proposing policies on land acquisition and border security, and discussed how to handle important military and national affairs.

He also arranged new equipment, built a granary, set grain prices, calculated salt transport, and established a system for collecting taxes.

There were more than fifty suggestions like this one that would benefit the country internally and ensure border security, and all of them were adopted by the emperor.

In the tenth year of Taishi, Empress Wuyuan Yang Yan passed away. Empress Yuan's tomb will be moved to Junyang Mausoleum.

According to the old funeral system, the emperor and his ministers could take off their mourning clothes after the burial.

The Secretary of State submitted a memorial, suggesting that the Crown Prince should also take off his mourning clothes.

Du Yu suggested that the crown prince should observe the ancient mourning system and mourn for three years. The emperor followed this advice.

In the autumn of the fourth year of Xianning, heavy rains hit the counties of Yan and Yu, causing large-scale flooding and locust swarms in the areas ruled by the Western Jin Dynasty. Du Yu presented his disaster relief plan twice.

These two memorials collected in "Book of Jin" are important documentary materials for later generations to study the social and economic conditions of the Jin Dynasty.

Du Yu was in the palace for seven years, and he carefully handled countless state affairs, which earned him praise from the court and the public. The name "Du Wuku" meant that Du Yu had everything in his mind.

At that time, Emperor Wu secretly formulated a plan to destroy Wu, and many court officials had different opinions. Only Du Yu, Yang Hu, and Zhang Hua agreed with Emperor Wu.

When Yang Hu was seriously ill, he recommended Du Yu to replace him, so he was given the title of General Pingdong and concurrently the Commander of the Southern Expedition Army.

In November of the fourth year of Xianning, after Yang Hu died, Du Yu was appointed as the General of the Southern Expedition and the Commander-in-Chief of the Military Affairs of Jingzhou, and was granted the Chariot of Pursuit and the second son-in-law.

After Du Yu took office, he repaired the armor and soldiers, showed off his military power, selected an elite army, attacked Zhang Zheng, the governor of Wu Xiling, and defeated Zhang Zheng's army. Because of his meritorious service, he was granted an additional 365 households.

In order to test the strength of the Eastern Wu's defense, he organized hundreds of elite soldiers to cross the river by boat and launch a surprise attack on the defense area of ​​Zhang Zheng, a famous general of the Eastern Wu and the governor of Xiling.

Many enemy troops were captured and a large amount of military supplies were seized.

Then, he used a strategy of sowing discord to make Sun Hao, the last emperor of Eastern Wu, replace Zhang Zheng and send Liu Xian, the governor of Wuchang, to guard the river defense.

The Dongwu Jiang defense force had just changed its generals, and the upper and lower levels were alienated, and its combat effectiveness was further weakened.

Du Yu saw that the time was ripe, so he submitted several petitions to Emperor Wu of Jin in the fifth year of Xianning, requesting that he immediately send troops to attack Wu.

In the above table, he analyzed in detail the internal affairs and armaments of Eastern Wu, and refuted the view of some ministers in the court that the outcome of the attack on Wu was unpredictable and that it was better not to act rashly.

He said that Sun Hao of Eastern Wu was now tyrannical and incompetent, the government was in chaos, the officials were alienated, the soldiers had no fighting spirit, and the signs of defeat were already very obvious.

If we go out now, we will have a sure victory. The chance of failure is only 10%. The ancients said that speed is the most important thing in war. If we don't send out troops immediately, delaying the battle will not only delay the opportunity, but also make it difficult for the plan to be leaked.

Once Sun Hao was frightened and had to repair the city and strengthen the river defense, it would be too late to send troops and the situation would become even more difficult.

Emperor Wu of Jin agreed with Du Yu's opinion and decided to send troops to attack Wu immediately.

"In the first month of the sixth year of Xianning, Du Yu led a large army to Jiangling and ordered his generals to lead troops westward along the Yangtze River to cooperate with Wang Xuan's navy that came out of Badong and went eastward along the river to capture several cities in succession."

"He also sent a general with 800 elite soldiers to cross the Yangtze River in the dark and attack Lexiang by surprise."

"He ordered his soldiers to raise more flags, bluff, set fires along the mountains, and create false alarms to disrupt the morale of the Eastern Wu army."

"Taking advantage of the battle between Sun Xin, the governor of the Eastern Wu who was stationed in Lexiang, and Wang Rong, Du Yu ordered an ambush to be set up outside Lexiang City."

"When Sun Xin was defeated and fled back to Lexiang City, the Jin army mixed in with the defeated soldiers of Eastern Wu and entered Lexiang City and captured Sun Xin alive."

"The army praised Du Yu for his ability to defeat ten thousand enemies with his own strategy. Taking advantage of the victory, Du Yu ordered his army to attack Jiangling, which was defeated in one blow."

"After Jiangling was captured, the commanders of the various Jin armies gathered in Jiangling for a military meeting to discuss how to advance and destroy Wu."

"Ministers such as Jia Chong and Gou Xu believed that it was impossible to defeat Wu in the short term, and that an epidemic was about to break out, so they should wait until winter to fight again."

"Some people also thought that it was summer and the river water was rising, so it was not appropriate to launch a large-scale military campaign."

"Du Yu refuted these views, pointing out that the Jin army had just won a victory and its military power was greatly enhanced. If it immediately marched eastward, it would be unstoppable."

"After the Jiangling Conference, Du Yu marched southward and killed or captured more than 130 generals and local officials of the Eastern Wu."

"Du Yu held the imperial seal to pacify the people, appointed officials, and restored order."

"As the Jin army advanced eastward along the Yangtze River, the Wu army surrendered wherever they reached."

"When the enemy was at the gates, Wu's ruler Sun Hao surrendered, and the Eastern Wu was destroyed."

"Thus, the three-kingdoms situation came to an end and national unification was achieved."

"Du Yu was promoted to Marquis of Dangyang County for his meritorious service, and his fief was increased to 9,600 households. His son Du Dan was also granted the title of Marquis of Ting, with a fief of 1,000 households, and Du Yu was also given 8,000 pieces of silk."

"Let him continue to guard Xiangyang. After Du Yu returned to the town, he repeatedly told Sima Yan that his family had been officials for generations and that he thought martial arts was not his forte, so he requested to resign, but the court did not allow it."

"After the unification of the country, Du Yu devoted himself to developing agricultural production and building water conservancy projects to benefit the local people."

"He presided over the construction of an irrigation canal in present-day Henan Province, diverting the Feishui River and the Yushui River to irrigate more than 1 hectares of dry fields in sandy areas. The public and private sectors benefited, and the people were very pleased and respectfully called him Father Du."

"He also presided over the construction of a canal more than 1,000 li long between Jiangling and Baling, diverting the Han River's tributary, the Xiashui River, into the canal and connecting it with the Xiangshui River. This not only reduced the threat of floods in the lower reaches of the Han River, but more importantly, facilitated transportation between the north and the south."

"At that time, there was a ballad circulating in the Jiangnan area that said, 'There is no rebellion in the future because of Du Weng, who knows his wisdom, reputation and bravery?' This was the people's praise for his civil and military achievements."

"At the end of the fifth year of Emperor Wu of Jin's Taikang reign, Du Yu, who enjoyed great reputation in the court and the country, was promoted to the position of Sili Xiaowei."

"But he unfortunately fell ill on his way to take up his post and died in Deng County at the age of 63."

"Emperor Wu of Jin was deeply saddened and issued an edict to posthumously confer on him the title of General of the Southern Expedition and the title of Grand Master of the Imperial Court, and the posthumous title of Cheng."

"After Du Yu passed away, his family followed his last will and followed the example of Zichan, a famous minister in the State of Zheng during the Spring and Autumn Period, who held a simple funeral and buried him in the south of Shouyang Mountain outside Luoyang."

"In the 21st year of the Zhenguan reign, Emperor Taizong of Tang ordered 22 ancient sages and scholars to be honored with Confucius, including Du Yu."

"In the third year of Jianzhong, the envoy of etiquette, Yan Zhenqing, suggested to Emperor Dezong of Tang that 64 ancient famous generals be posthumously honored and temples be built for them to offer sacrifices, including Du Yu."

"In the fifth year of Xuanhe, the Song Dynasty followed the Tang Dynasty's practice and established temples for ancient famous generals. Du Yu was also among the 72 famous generals."

Bai Juyi: Du Yu not only had profound attainments in military affairs, but was also proficient in economics, politics, calendar, law, mathematics, history, and even calligraphy and engineering.

People at that time knew that Du Yu was knowledgeable and talented, so they gave him the nickname Du Wuku, which means that he was like an arsenal of weapons, with everything and knowing everything.

Excellent people are not scary, what is scary is that they still work very hard.

Du Yu often said that I could not establish moral values, but I could establish meritorious services and make statements.

You have to know that there are only a handful of people in history who have achieved all three goals, and Zeng Guofan is only half of them. Being able to accomplish one of them is enough to go down in history. Anyone who hears Du Yu say this would say that he is bragging.

After the death of the famous general Yang Hu, Du Yu took over and guarded Xiangyang.

As soon as Du Yu took office, he sent troops to launch a surprise attack on Xiling. After breaking through Xiling, he went downstream and captured Jingzhou. The destruction of Wu was inevitable.

However, Xiling Governor Zhang Zheng should not be underestimated. Du Yu used a strategy of killing someone with a borrowed knife, and Sun Hao withdrew Zhang Zheng.

The general was changed at the last minute and the morale of the army was unstable. Now was a good time to destroy Wu.

Du Yu wrote to Emperor Wu of Jin, requesting an attack on Wu, but his plan was foiled by the opposition, and Sima Yan decided to postpone it for a year.

Opportunities are rare and will never come back, which made Du Yu very anxious. He wrote another letter to analyze the situation.

Who knew that Jia Chong and others made another fuss, and Du Yu wrote a letter to the emperor for the third time, before Sima Yan made up his mind to destroy Wu.

Immediately afterwards, Sima Yan mobilized an army of more than 280 and attacked by both land and sea, and in AD he destroyed Wu.

This war not only ended the century-long chaos of the Three Kingdoms, but was also the only war of unification in the 400 years of the Wei, Jin, Southern and Northern Dynasties.

Thousands of years later, how many people can remember that the person who accomplished this feat was a man who couldn't even ride a horse or shoot an arrow?
In the second year after the conquest of Shu, Sima Zhao asked Jia Chong and others to reform the laws. In name, it was the joint efforts of Jia Chong and others, but in fact it was basically Du Yu who completed the annotations of the Jin Law independently.

Thanks to Du Yu's efforts, the new laws were not only simplified, but also easy to understand. Ordinary people could understand them at a glance and would not dare to violate them.

Du Yu said that he had no moral integrity, but on the contrary, he had the greatest moral integrity.

During his tenure as Minister of Revenue, Du Yu wrote many letters to the emperor, offering many suggestions to Sima Yan, all of which were related to governing the country and strengthening the army.

The scope involved is also very broad, such as managing salt transportation, rebuilding border defenses, formulating taxes, adjusting prices, etc.

Du Yu established schools, repaired water conservancy sites, and diverted the Fei and Yu rivers to irrigate the fields. The people benefited from this and called him Du Fu.

Heavy rains hit Yanyu and other provinces, coupled with a locust plague, and the people suffered terribly.

After personally investigating the situation, Du Yu wrote two memorials to the emperor, proposing practical disaster relief measures. He also suggested lending some oxen to the remaining people so that they could resettle their homes and start their own businesses.

In fact, he can be compared with Wang Yangming and Zhuge Liang and can be called a perfect man with three characteristics.

It may be because of the novel, many people in the Three Kingdoms are too famous, which overshadows Du Yu. (End of this chapter)
