Sun Chen
In 258, Sun Chen deposed the second Wu emperor Sun Liang and replaced the latter with Sun Xiu. Sun Xiu was unhappy that Sun Chen monopolised state power so he plotted with the minister Zhang Bu to eliminate Sun Chen. Zhang Bu told the emperor, "Ding Feng may not be proficient in administrating civil affairs, but he is an outstanding strategist and is capable of making important decisions." Sun Xiu then summoned Ding Feng and told him: "Sun Chen usurps state power and is plotting treason. I want you to help me eliminate him." Ding Feng replied: "The Imperial Chancellor (Sun Chen) and his brothers have many supporters. Not everyone in the imperial court is on our side. We cannot confront them directly. I suggest that Your Majesty order your soldiers to kill him during the Laba Festival." Sun Xiu followed Ding Feng's plan and pretended to invite Sun Chen to the palace to celebrate the Laba Festival. When Sun Chen stepped inside, Ding Feng and Zhang Bu signalled to the imperial guards to kill him. For his contributions, Ding Feng was promoted to the position of General-in-Chief () and received the additional appointments of Left and Right Protector-Generals ().
