Who conspired with Tian fen to rebel?

It was Liu An, the king of Huainan, who plotted against Tian Fen.

In the second year of Emperor Wu of the Han Dynasty, the local king of Zuowei Liu went to Beijing from Huainan to meet the newly elected little emperor. Liu Che showed great enthusiasm for his uncle's arrival. He dined alone with Liu An, and listened to the learned King of Huainan talking about the past and the present. He talks about it from morning till night, but he seems to want more.

This time in Chang 'an, Liu An and Uncle Tian Fen hit it off again. For some unknown reason, this guy Tian Fen even said to Liu An, "Today, the emperor has no prince. You are the grandson of Emperor Gao. Do good deeds, accumulate virtue, be knowledgeable and versatile, and be famous all over the world. When the emperor dies in the future, who else can be king except you? " Some people are smart all their lives and confused for a while. Tian Fen this obviously flawed touting disgusting words, huai nun tzu listen to not to come out, really thought it was for him. Don't people with great wisdom like him think that Liu Che is several decades younger than his Liu An? Under normal circumstances, how can he die after he dies? This is one; Second, when Tian Fen said this, Emperor Wu was still young, and it was normal to have no prince, but that doesn't mean he won't have a prince in the future. Isn't it a joke to let an old man wait to take over the children's class? But Liu An couldn't see Tian Fen's intention. Power made him dull and confused. For that so-called good word, Liu An was so excited that he secretly sent a lot of Abel Tamata powder.
