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

【Start popularizing science about Hongwu’s four major cases, the last one!】

【The blue jade case!】

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

【And as a famous founding general of the country, why was Lan Yu killed?】

【It also implicated tens of thousands of people】

【Given the situation at that time, Lan Yu must die!】

【No matter how rich his credit is, no matter how gentle and thrifty he is, he must die!】

【...】

【Lan Yu's sister, Lan, was the wife of Chang Yuchun, King of Kaiping. In her early years, Lan Yu had been working under her brother-in-law, and she reached the rank of chief military officer in the Governor's Palace.】

【So Lan Yu is not a commoner who made a fortune, he is a"connected household" who has a brother-in-law in the army."】

【In 1369, her brother-in-law Chang Yuchun died of illness, and Lan Yu left the care of her brother-in-law Chang Yuchun.】

【In 1371, Prince Zhu Biao married Chang Yuchun's daughter, Chang. Lan Yu was Chang's 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 in the westward expedition to Sichuan and won a great victory.】

【In 1372, Lan Yu served as a vanguard officer in Xu Da's Northern Expedition to Mongolia and repeatedly performed extraordinary feats. In this year, Lan Yu became a rising star of the second-generation military group of the Ming Dynasty.】

【Lan Yu later put down the Hebei rebellion in 1374 and the Xibo rebellion in 1378.】

【Finally, in 1379, he was granted the title of Marquis of Yongchang 387】

【Lan Yu was very supportive of her sister and relied on her military exploits to become the leader of the second generation of generals in the Ming Dynasty.】

【In 1381, Lan Yu participated in the Yunnan War and not only captured Kunming without a single blow, but also quickly captured Dali.】

【In the same year, Lan Yu's daughter was canonized as the Princess of Shu. Lan Yu became Zhu Yuanzhang's marriage partner, and she first showed her prominence in the Ming Dynasty's military system.】

【In 1387, Lan Yu followed Song Guogong Feng Sheng on an expedition to Liaodong to eliminate the remaining forces of the Yuan Dynasty in Liaodong.】

【After the victory in the Battle of Liaodong, Feng Sheng was convicted and arrested on his way home.】

【Lan Yu was promoted to general to deal with the aftermath.】

【At this time, Lan Yu was a sword that Zhu Yuanzhang trusted very much, confirming his leadership status in the Ming army.】

【In the same year, the head of the Chang family, Chang Mao, was exposed for his illegal activities in the military and was demoted to Longzhou. Lan Yu, who was at the height of his power, became the actual spokesperson of the Chang family.】

【In 1388, Lan Yu independently led the Northern Expedition】

【Responsible for the conquest. Tuogu Si Timur, the successor of the Northern Yuan Dynasty】

【This was the first time he went to war as a commander instead of a general, and he became famous in one battle. The Battle of Yuerhai stewed the Yuan Dynasty royal family in a pot. The Yuan Dynasty was completely ended, and the grassland was returned to the tribal era.】

【And Lan Yu has an arrogant personality】

【There was no etiquette when facing Zhu Yuanzhang】

【Now that he has achieved great success, he starts to behave wildly】

【He even secretly embezzled the jewelry seized from the Northern Expedition, and insulted the imperial concubine of the Yuan Dynasty, causing her to hang herself.】

【In the same year, the class teacher returned to the imperial court and passed by Xifeng Pass.】

【Because he knocked on the door in the middle of the night and received no timely response, Lan Yu sent troops to break through Xifeng Pass, shocking the government and the public.】

【Both of these things made Zhu Yuanzhang unhappy.】

【Therefore, Zhu Yuanzhang changed the title originally given to Lan Yuliang to Duke of Liang.】

【Lan Yu, who became the Duke of Liang, successively committed cross-border acts such as beating the censor, seizing civilian fields, and arbitrarily dismissing and promoting officers in the army.】

【Zhu Yuanzhang knew it, but there was no serious punishment.】

【Because he is training a team for Prince Zhu Biao, and Lan Yu is a useful knife】

【On February 8, 1393, Jinyiwei commander Jiang Wei suddenly reported Lan Yu for rebellion!】

【Zhu Yuanzhang didn't even give Lan Yu a chance to defend himself.】

【Peel directly on February 10th】

【More than 10,000 Lan Yu's cronies were also implicated and executed, which is known as the"Lanyu Case" in history."】

【For such a big case, Zhu Yuanzhang concluded the case and executed him in just 2 days】

【It can be seen that Zhu Yuanzhang was very urgent to kill Lan Yu】

【Lan Yu reached the pinnacle of her life in 1388 and was killed in 1393. 】(To read exciting novels, go to Feilu Novel Network!)

【Only 5 years】

【To be said to be domineering, as early as 1388, Lan Yu destroyed the city of the Ming Dynasty.】

【It's like a rebellion and should have been killed long ago】

【Compared with the subsequent seizures of civilian fields, it was really not a problem in the era of imperial power, and it did not involve tens of thousands of people suffering. (cdfj)】

【Lan Yu was killed, the direct reason was 1392】

【A major event occurred that year that shocked the entire Ming Dynasty.】

【In April 1392, Prince Zhu Biao died of illness.】

【As early as 1377, Zhu Yuanzhang ordered all political affairs and punished the prince. Then he reported the news and asked Zhu Biao to visit the ministers to practice state affairs.】

【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 commander carefully trained by Zhu Yuanzhang for Zhu Biao】

【A person who often makes mistakes, can find excuses, and is very capable of fighting and making meritorious deeds】

【Isn't this the emperor's favorite general in the world?】

【This also explains why Lan Yu kept making mistakes but Zhu Yuanzhang did not deal with them.】

【This is a controllable knife that Zhu Yuanzhang left for the prince.】[]

【However, Zhu Biao's sudden death caught Zhu Yuanzhang, who was already in his twilight years, by surprise.】

【At this time, Zhu Yuanzhang wanted to pass on the throne and ensure that the eldest son succession system he had set was observed. 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, he created a huge risk. 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. Soon after Chang's eldest son Zhu Xiongying died in 1382】

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

【Zhu Yunwen succeeded to the throne, in theory, he was stealing the throne from Zhu Yunxi】

【If Zhu Yunwen succeeds to the throne, and Lan Yu himself has a large number of troops, will he be able to accept someone with his nephew's son's throne, given his character?】

【Lan Yu has the kind of character that smashes her own city gate if she disagrees with her】

【As soon as Zhu Yuanzhang died, he might take Zhu Yunxi and destroy Zhu Yunwen】

【Therefore, if Zhu Yunwen wants to sit on the throne, 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 comes down to age. There are too many cases in history where emperors were young and powerful ministers seized power.】

【Zhu Biao passed away, and Zhu Yunxi was only 14 at the time.】

【If he ascends the throne, Lan Yu will definitely become a powerful minister, and it is not impossible to wear a yellow robe. With so many adopted sons in his army, then by then the Zhu family will have to be named Lan】

【Zhu Yuanzhang was unwilling to take this risk】

【So in the end, Zhu Yuanzhang looked at Lan Yu and thought: Go to hell!】

【This knife is no longer needed. If we use it again, we will hurt ourselves!】
