I make a popular science video and all the emperors learn from it!

[Start the four major cases of science popularization and Hongwu, the last case!]

【Blue Jade Case!】

[Lan Yu (?-1393), a native of Dingyuan County, Fengyang Prefecture, the wife and brother of King Chang Yuchun of Kaiping, and the founding general of the Ming Dynasty. 】

[And Lan Yu, as the founding general, why was he killed?]

[Tens of thousands of people were also implicated because of this.] 】

[With the situation at that time, Lan Yu must die!]

[No matter how thick his merit book is, no matter how gentle and frugal he is, he must die!]

【...】

[Lan Yu's sister Lan Shi is the wife of Chang Yuchun, King of Kaiping, and Lan Yu has been working under her brother-in-law in her early years, and she has achieved the highest level of the general military level of the Metropolitan Governor's Mansion (qian). 】

[So Lan Yu is not a cloth cloth to make a fortune, he is a "relation" of his brother-in-law in the army. 】

[In 1369, her brother-in-law Chang Yuchun died of illness, and Lan Yu escaped from the protection of her brother-in-law Chang Yuchun. 】

[In 1371, the crown prince Zhu Biao married Chang's daughter Chang Yuchun, and Lan Yu was Chang's maternal uncle. 】

[If Zhu Biao ascends the throne, Lan Yu will be a veritable uncle of the country. 】

[In the same year, Lan Yu followed Fu Youde and won a great victory in the westward expedition to Sichuan. 】

[In 1372, Lan Yu served as a pioneer officer in Xu Da's Northern Expedition to Mongolia, and made many miraculous achievements, and in this year, Lan Yu became the new star of the second generation of military groups in the Ming Dynasty. 】

[Lan Yu later put down the rebellion of Hebei in 1374 and the rebellion of Xifan in 1378. 】

[Finally, in 1379, he was crowned Marquis of Yongchang 387. 】

[Lan Yu is very angry with her sister, relying on military merits, she became the leader of the second generation of generals in the Ming Dynasty. 】

[In 1381, Lan Yu participated in the Battle of Yunnan, not only took Kunming without blood, but also quickly took Dali into his pocket. 】

[In the same year, Lan Yu's daughter was canonized as the princess of Shu, and Lan Yu became Zhu Yuanzhang's marriage object, and in the Ming military system, she began to show her edge. 】

[In 1387, Lan Yu followed Feng Sheng, the Duke of Song, on an expedition to Liaodong to purge the remnants of the Yuan Dynasty in Liaodong. 】

[After the victory of the Battle of Liaodong, Feng Sheng was arrested on the way to victory. 】

[Lan Yu was promoted to a general and carried out the aftermath. 】

[At this time, Lan Yu is a knife that Zhu Yuanzhang trusts very much, and he confirms his leader-level status in the Ming Army. 】

[In the same year, Chang Mao, the head of the Chang family, was exposed for his lawlessness in the army, and was demoted to Longzhou, like the blue jade in the sky, and became the actual spokesperson of the Chang family. 】

[In 1388, Lanyu independently led the Northern Expedition. 】

[Responsible for the conquest of the Northern Yuan heir Jun Tugusi Timur. 】

[This is the first time he went out as a handsome, not a general, and became famous in the first battle, the battle of fishing Erhai, the royal family of the Yuan Dynasty was stewed in a pot, the Yuan Dynasty was completely ended, and the grassland was beaten back to the tribal era. 】

[And Lan Yu has an arrogant personality. 】

[When facing Zhu Yuanzhang, there is no etiquette. 】

[Now that he has made great achievements, his behavior has begun to be presumptuous. 】

[He actually embezzled the jewels seized by the Northern Expedition without permission, and insulted the imperial concubine of the Yuan Dynasty, causing her to hang herself. 】

[In the same year, the class teacher returned to the court and passed through Xifeng Pass. 】

[Due to knocking on the door in the middle of the night and not getting a timely response, Lan Yu sent troops to break through Xifeng Pass, shocking the government and the opposition. 】

[These two things made Zhu Yuanzhang dislike. 】

[Therefore, Zhu Yuanzhang changed the title of Lan Yuliang Guogong to Liangguo Gong. 】

[Lan Yu, who became the Duke of Liangguo, successively crossed the line by beating Yushi, forcibly occupying people's land, and removing and promoting officers in the army without authorization. 】

[Zhu Yuanzhang knew, but there was no major punishment. 】

[Because he is training the crown prince Zhu Biao, and Lan Yu is a good knife. 】

[On February 8, 1393, Jin Yiwei commanded Jiang Zhen to suddenly denounce Lan Yu's rebellion!]

[Zhu Yuanzhang didn't even give Lan Yu a chance to plead. 】

[Peel directly on February 10th.] 】

[More than 10,000 Lan Yu's cronies were also implicated and killed, known as the "Lan Yu Case" in history. 】

[In such a big case, Zhu Yuanzhang closed the case and was executed in only 2 days. 】

[It can be seen that Zhu Yuanzhang is very urgent to kill Lan Yu. 】

[Lan Yu reached the peak of her life in 1388 and was killed in 1393. (Read the violent novel, go to the Feilu Novel Network!)

[It's only been 5 years.] 】

[If you want to talk about Bahu, as early as 1388, Lan Yu smashed the city of the Ming Dynasty. 】

[It's already like a rebellion, and it should have been killed a long time ago.] 】

[Compared with this, the era of imperial power is really not a thing, and it does not implicate tens of thousands of people to suffer. (cdfj)】

[Lan Yu was killed, the direct cause was in 1392.] 】

[A major event occurred that shook the entire Ming Dynasty. 】

[In April 1392, the crown prince Zhu Biao died of illness. 】

[As early as 1377, Zhu Yuanzhang ordered all political affairs and punished the prince, and then let Zhu Biao come to the ministers and practice national politics. 】

[When Zhu Biao died, he had actually handled the emperor's government affairs for 15 years. 】

[Lan Yu's rapid rise has a lot to do with the fact that he is the uncle of Zhu Biao's wife. 】

[Lan Yu can be said to be a military general carefully trained by Zhu Yuanzhang for Zhu Biao. 】

[A person who often makes mistakes, can have a handle, and is very capable of fighting and making meritorious contributions. 】

[Isn't this the emperor of the whole world, the favorite general?]

[This also explains why Lan Yu keeps making mistakes, but Zhu Yuanzhang doesn't deal with him. 】

[This is a controllable knife left by Zhu Yuanzhang to the prince. 】[]

[However, Zhu Biao's sudden death caught Zhu Yuanzhang, who had entered his twilight years off guard. 】

[At this time, Zhu Yuanzhang wanted to pass on the throne and ensure that the primogeniture inheritance system he had set was observed, and Lan Yu became his biggest obstacle. 】

[The reason why blue jade became an obstacle was because of Zhu Yuanzhang's decision in September 1392. 】

[At that time, when Zhu Yuanzhang established Zhu Yunwen as the emperor's grandson, Lan Yu was bound to die. 】

[After Zhu Yuanzhang chose Zhu Yunwen to take over, it caused a great risk, and this risk forced Zhu Yuanzhang to kill Lan Yu. 】

[Lan Yu's niece Chang Shi died as early as 1378 after giving birth to Zhu Yunxi, and soon Chang's eldest son Zhu Xiongying died in 1382. 】

[The only link between Zhu Biao and Lan Yu is only Zhu Yunxi. 】

[Zhu Yunxi's succession to the throne is theoretically to grab Zhu Yunxi's throne. 】

[If Zhu Yunwen succeeds to the throne, Lan Yu himself has a heavy army, and in the face of a person who robs his nephew's daughter for the throne, will he obey with Lan Yu's character?]

[Lan Yu's character of smashing his own city gate without saying a word. 】

[As soon as Zhu Yuanzhang dies, he may pull Zhu Yunxi and destroy Zhu Yunxi. 】

[Therefore, Zhu Yunwen wants to sit on the throne, and Lan Yu must die!]

[In Zhu Yuanzhang's eyes, there is no doubt about this. 】

[But why didn't Zhu Yuanzhang directly establish Zhu Yunxi?]

[In fact, it is out of age, there are too many emperors in history who are young and powerful. 】

[Zhu Biao died, and Zhu Yunxi was only 14 at the time. 】

[If he ascends the throne, Lan Yu will inevitably become a powerful minister, and it is not impossible to stage a yellow robe, there are so many righteous sons in his army, then by that time the Zhu family will have the surname Lan. 】

[Zhu Yuanzhang is unwilling to take this risk. 】

[So in the end, Zhu Yuanzhang looked at Lan Yu and thought: You go die!]

[This knife is no longer needed, and if we use it again, we will hurt ourselves!]
