孫休
Although Sun Xiu approved Sun Chen's request, he suspected that Sun Chen wanted to seize control of Wuchang and then rebel against him. Another official, Wei Miao (), also warned Sun Xiu that Sun Chen might be plotting treason when he asked to leave for Wuchang. Besides, there were also widespread rumours that Sun Chen was disloyal towards Sun Xiu. Sun Xiu then conspired with Zhang Bu and another general Ding Feng to assassinate Sun Chen at a feast during the Laba Festival (8th day of the 12th lunar month). Sun Chen got wind of the plot and became apprehensive, but still attended the feast, where he was captured by Zhang Bu and Ding Feng's soldiers. When Sun Chen begged for his life and pleaded to be exiled to Jiao Province or reduced to the status of a slave, Sun Xiu refused to spare him and told him that he did not spare Teng Yin or Lü Ju either when he came to power in 256. Sun Xiu then ordered Sun Chen to be executed along with his family members.
