陸凱
Chen Shou, the third-century historian who wrote Lu Kai's biography in the "Sanguozhi", mentioned that during his research on information about Lu Kai, he came across a memorial allegedly written by Lu Kai to Sun Hao. This memorial originated from sources in Jing and Yang provinces. However, when Chen Shou cross-checked with sources from the Wu region, he was unable to verify the authenticity of the memorial. Nevertheless, Chen Shou believed that the memorial was authentic from its tone and writing style. He theorised that Lu Kai most probably wrote the memorial but did not present it to Sun Hao and kept it hidden until he finally decided to show it to Dong Chao () before his death. Chen Shou did not include the memorial in the main text of Lu Kai's biography because of its dubious origin. However, he was impressed after reading the memorial, and believed that it could serve as a lesson for future rulers, hence he included it as an addendum at the end of Lu Kai's biography.
