満寵
In the second incident, Yang Biao (), the Grand Commandant, was arrested and imprisoned for allegedly conspiring with Yuan Shu, a warlord who rebelled against the Eastern Han dynasty. Man Chong, who was in charge of interrogating Yang Biao, received requests from his colleagues Xun Yu and Kong Rong to refrain from using torture on Yang Biao during the interrogation. However, Man Chong ignored them and did everything by the book. A few days later, Man Chong reported to Cao Cao: "Yang Biao had nothing to say when I interrogated him. Before executing a criminal, we must first produce evidence of his guilt and show it to the public. Yang Biao is a reputable man. If we execute him without sufficient evidence to show that he is guilty, the people will lose faith in us. I hope you will reconsider your decision carefully and not be too hasty in ordering Yang Biao's execution." Cao Cao then released Yang Biao. Xun Yu and Kong Rong were initially angry with Man Chong when they found out that he tortured Yang Biao during the interrogation. However, they became more amiable towards him after they heard what he told Cao Cao.
