陸凱
At the time, Sun Hao had an attendant, He Ding (), who was notorious for fawning on the emperor, speaking ill of officials behind their backs, and giving unfair preferential treatment to those who were close to him. Lu Kai once reprimanded him: He Ding bore a grudge against Lu Kai for this, and he constantly thought of ways to get back at Lu Kai. However, Lu Kai remained unfazed and continued to perform his duties in a professional and impartial manner. He continued to show his sincerity and loyalty towards Sun Hao by being candid and not mincing his words whenever he gave advice to the emperor.
