Almost got killed
Fan Kuai followed Liu Bang all the time, and he was Liu Bang's favorite. Later, he married Lu Houmei and gave birth to a son Fan Heng, so his relationship with the emperor became closer. But because he was Lv Hou's brother-in-law, he was almost punished.
In BC 195, the high-impedance Liu Bang returned from defeating the rebel Ying Bu and fell ill after a traumatic attack. No sooner had he returned to Chang 'an than he heard that Lu Wan, the prince of Yan, had defected, so he sent Fan Kuai as the prime minister to make a crusade. After Fan Kuai left, someone said to Gaozu, "Fan Kuai and Lv Hou are in cahoots and want to wait until the emperor is 100 years old.
The emperor can't help but be vigilant. "High-impedance of Lv Hou's failure to intervene in failure, would have been dissatisfied. I heard that Lv Hou colluded with her brother-in-law Fan Kuai again, and immediately felt that the situation was serious. He has decided to change his position and is considering things with Chen Ping. Finally, he took Chen Ping's advice, sent a letter to Fan Kuai in the name of Chen Ping, and secretly took General Zhou Bo to the car.
When we arrived at the barracks, we announced that Fan Kuai would be beheaded and replaced by Zhou Bo. Before arriving at the military camp in Fan Kuai, Chen Ping ordered people to build a high platform as a place to pass orders, and also sent people to hold festivals (a symbol) to call Fan Kuai. Fan Kuai learned that Chen Ping, a civil servant, was the only one who came, thinking that he was just delivering a routine decree.
I didn't think much, and immediately rode alone to meet the imperial edict. Unexpectedly, the frequency of the military commander suddenly appeared behind the stage, and Fan Kuai was about to be arrested and nailed into the prison car. Frequency immediately rushed to Zhong Jun tent again to escort the van back to Chang 'an instead of Fan Kuai and Chen Ping.
Extended data
Sima Qian recorded very clearly that Fan Kuai was on Lv Hou's side, and Liu Bang killed all the half-recruited queens, and his suspicion of Lu Yi became more and more serious. Liu Bang loves Qi's wife and likes her son Ruyi Zhao. Liu Bang thinks Mrs Qi is too weak. If Liu Bang dies, Fan Kuai will probably attack their mother and son.
But this is not the main reason. The main reason is that Liu Bang is worried about Liu Jiangshan's instability. First of all, Fan Kuai has a special status (he and Liu Bang are brother-in-law). This relationship not only makes Liu Bang "reuse" him more, but also makes Liu Bang more afraid of him.
Secondly, Fan Kuai is a highly prestigious general in the army, second only to Han Xin and frequency. He can not only lead troops to fight, but also take the lead. He has excellent command ability, and he has a good political vision. He is by no means a rough warrior.
