At that time, a minister named Guan Fu insulted other ministers at a banquet and accused the emperor of swearing. Emperor Wu of the Han Dynasty was very angry, but Dou Ying interceded for the irrigator, saying that someone had deliberately set him up. But it did happen after Emperor Wu of the Han Dynasty sent someone to investigate. Dou Ying lied, so he was detained for cheating the monarch. Instead of saving the man who poured water, Dou Ying put himself in and asked his nephew to take out Han Jing's legacy, hoping that Emperor Wu would bypass himself for his father's sake. However, the posthumous edict of Emperor Han Jing was not filed in the palace, and only this one was in the hands of Dou Ying.
Therefore, Dou Ying not only committed the crime of deceiving the monarch, but also forged the testamentary edict. Many ministers impeached Dou Ying and were finally beheaded. As can be seen from the above, there are many doubts about Dou Ying's death, but from the perspective of Emperor Wu, Dou Ying must die. Although after Dou Taihou's death, Emperor Wu actually took control of the army, Wei Qing, the leader of the body guard, was also one of our own. So he can rest easy? No, but many ministers have followed Dou Taihou, and Dou Ying, a Dou family, is one of them. Therefore, Emperor Wu of the Han Dynasty wanted to really rectify the imperial court, so that the upper and lower levels were self-respecting and centralized, so he had to get rid of Dou Ying.
The imperial edict of Emperor Jing of Han Dynasty, if its authenticity is acknowledged, is a curse to Emperor Wu of Han Dynasty. So when Dou Ying, the minister who entrusted orphans, wanted to rebel, he thought that Liang Wudi was not qualified to be emperor, that is to say, he was orthodox, and even Liang Wudi, who opposed Dou Ying, rebelled. So Emperor Wu had to kill Dou Ying.
