蔡邕
In 191, during the reign of Emperor Xian ( 189–220), Ma Midi was promoted to Grand Commandant (太尉) by Dong Zhuo, the warlord who controlled the Han central government and the figurehead Emperor Xian from 189 to 192. In 192, Dong Zhuo was assassinated in Chang'an by Lü Bu and Wang Yun, who became the new head of the central government. When Cai Yong allegedly expressed grief at Dong Zhuo's death, Wang Yun had him imprisoned and sentenced to death. Ma Midi and other officials pleaded for leniency on Cai Yong's behalf, but Wang Yun refused and had Cai Yong executed.
