Liu Bang revolted in Pei County, and Lu Wan made a guest appearance with Liu Bang. Later, he entered the customs with Liu Bang, and was named as a general. Chu and Han fought for hegemony and were named as Qiu. In July of the fifth year of Emperor Gaudi (202 BC), Lu Wan was recommended as the Prince of Yan by Han Xin and other ten people for his rebellion against Tibetan tea. Since then, Lu Wan has twice taken the lead in proposing to make Liu's children king to show his loyalty to the Han Dynasty. Once, Liu Ruyi was created as the Prince of Zhao by the acting king, and the acting king was vacant. Lu Wan also proposed that Liu Heng, another son of Liu Bang, be king instead of him. As a king with a different surname, Liu Bang can promote the realization of the strategy of replacing the king with the same surname with such positive actions, which will naturally be particularly appreciated. However, this pair of brothers, close friends, finally went to the opposite side. The fuse that led to all this was another person-Chen Yi.
Because Liu Bang's princes Liu Ruyi and Liu Heng were too young to go to Yue, Liu Bang appointed these two countries as Chen Si to take charge of their affairs. Because there is no secret to prepare rebellion with Han Xin, they fought against Korea on the land of Zhao and Dai. While the state of Yan was in the north of Dai and Zhao, when Liu Bang personally led the troops to make a personal expedition, he ordered Lu Wan to attack Chen Yi from the northeast.
In order to win, Shang Chen sent someone to ask the Huns for help, but the Huns just married into the Han Empire and didn't want to help a rebel of the Han Empire, but he didn't say that he wouldn't send troops. After Lu Wan knew it, he immediately sent John Zhang, who knew the Huns, to Xiongnu, explaining to Modu that Chen Yi's soldiers had been defeated and Xiongnu should not join the aid. But John Zhang met a man in Xiongnu, who changed his mission and the fate of Lu Wan. This man's name is Wei Yan
Wei Yan (Zangyan) is the son of Zangcha, the defeated former Prince Yan. He fled to Xiongnu and became a rebel among Han officials. He said to John Zhang, the reason why you are reused by the prince is because you are familiar with the Huns, and the prince is still here, because other recruited c's want to rebel and have no time to take care of him. Now if Chen Yi is caught, Liu Bang will send troops to attack the Prince, and you and the Prince will be prisoners. Now, only by supporting Chen Si and uniting with Xiongnu can Emperor Xian of Han dare not attack easily, and the prince will always be a prince. John Zhang felt right, so he suggested that modu chanyu send troops to help Chen Yi. Luwan didn't wait for John Zhang to come back. He heard that the Huns sent troops to help Chen Yi and thought that John Zhang had defected. He reported to Liu Bang that John Zhang had defected to the enemy and demanded that his family be executed. And just finished the report, John Zhang came back and told him what Wei Yan said. Lu Wan wanted to think about the fate of Han Xin, Peng Yue and other c's, and felt reasonable, so he agreed with Wei Yan's statement and asked someone to say that John Zhang killed him.
However, the rebellion in Chen Si was quickly put down, and it was also discovered that Luwan was connected with Xiongnu and secretly assisted Chen Si. At first, Liu Bang found it incredible that his brother had defected. After verification, he shot the wound with an arrow and sent Fan Kuai to capture Lu Wan. When Lu Wan knew about it, he heard that the Yanjun couldn't resist Fan Kuai and finally took his family to the Great Wall. He intends to offer a humble apology after Liu Bang's illness. Unexpectedly, ten days later, he heard the news of Liu Bang's death. For several days, Luwan lingered at the foot of the Great Wall. Finally, in desperation, he chose a road of no return: leading the people to the Huns. Finally, he was named the East Gourd King by modu chanyu. Luwan was far away in the desert, missing his motherland, and died of depression a year later.
Alas, these two fellow villagers were born on the same day in the same year, grew up together, became brothers, rebelled against Xiang Yu, the king of Chu, and finally defeated Xiang Yu. But in the end, because of suspicion, I came to the point where I met with a knife and a gun, which was sad and regrettable.
