Ji Kang
One major case in Han dynasty was the case of Yang Yun (杨恽). Emperor Xuan first discharged him from his position in the government under the accusation of defamation. In 54 BC, he was sentenced to death through waist chop because of his complaints on his unfair treatment written in a letter for his friend Sun, which was considered disrespectful and outrageous to the Emperor. Affected by this, his friends who were still in court, were also discharged from their positions. In 208, Kong Rong, a lead figure of the Seven Scholars of Jian'an in late Eastern Han dynasty, was killed by warlord Cao Cao for his letters to Cao disagreeing and criticizing his rule and practice, including Cao's ban on alcohol for its potential negative impact on the nation. His wife and two sons were also killed. In Three Kingdoms period, the death of Ji Kang was also related to his writing. In response to Sima Zhao's offer of a position as civil official, Ji Kang wrote a letter ("与山巨源绝交书") expressing his refusal of pursuing any political career. This letter, however, later provided justification for the advice of Zhong Hui, the official who conveyed the offer for Sima Zhao to Ji Kang, to sentence Ji Kang to death.
