At that time, Han Anguo was an official in the State of Liang, and was arrested by the King of Liang because he offended the powerful people in the DPRK. There is no record in the history books of what crimes South Korea committed. From it, we can see that it was actually Liang Wang who didn't like Han Anguo, so he found a reason to get rid of Han Anguo.
Han Anguo was ill-treated when he was in prison. The jailers in the prison looked down on him at that time. One of the jailers is Tian Jia. His attitude towards Han Anguo is very bad. He thinks that Han Anguo has become a prisoner, with nowhere to turn over and can bully him at will. At that time, Han Anguo was very angry with Tian Jia's behavior and said to Tian Jia, aren't you afraid that I will turn over later? Hearing this, the family laughed and said that even if Han Anguo turned over in the future, he would not be afraid. At that time, Han Anguo described his present situation as a resurgence, and his possible future experiences as a resurgence.
But what Tian Jia didn't expect was that although Liang Wang didn't like Han Anguo at that time, Dou Taihou liked Han Anguo very much. At that time, Dou Taihou thought that Han Anguo had made contributions to the country, so he was released from prison. Not only that, but also promoted him as acting prime minister. Since a prisoner once became the prime minister of the dynasty, his position has been greatly improved, and Han Anguo really turned over. When Han Anguo came out of prison, he didn't embarrass the family. Instead, he generously forgave Tian Jia's behavior. This story has gradually become a resurgence idiom.
