孙皓
According to one account, sometime in January or early February 267, Lu Kai plotted with Ding Feng and Ding Gu () to overthrow Sun Hao while he was visiting the imperial ancestral temple, and replace him with Sun Xiu's son. Lu Kai then secretly instructed an official to recommend Ding Feng to lead the 3,000 imperial guards escorting Sun Hao to the temple. However, Sun Hao rejected the suggestion and chose Liu Ping () instead. Lu Kai and the others then contacted Liu Ping and asked him to join the plot. Although Liu Ping refused to participate, he also promised them that he would not reveal anything. Without Liu Ping's help, the plot could not be carried out. Around the same time, an imperial clerk Chen Miao () warned Sun Hao that there were ominous signs (e.g. dark clouds but no rain, winds changing direction) so Sun Hao, being superstitious, ordered his guards to be on high alert.
