Yang Hu
The "Han Jin Chunqiu" () further described this uncanny friendship between Lu Kang and Yang Hu. After returning to Jin territory, Yang Hu started promoting morality and civility, and many Wu citizens were impressed with him. Lu Kang told the Wu forces stationed at the Wu-Jin border: "If they govern with virtue and we administer our state like tyrants, we will lose the war without even having to fight. I hope that you can guard the border well and not stir up problems over trivial matters." The Wu-Jin border experienced peace and stability as both sides actively practised "détente" and got along harmoniously with each other. If cattle from one side accidentally strayed across the border, the other side would allow the owners to cross the border and retrieve their cattle. During hunting expeditions at the border, if the citizens of either side were injured, the other would send them home safely. When Lu Kang fell sick, he asked for medicine from Yang Hu. Yang Hu obliged and said: "This medicine is of fine quality. I prepared it myself. I haven't tried it myself when I heard that you are ill so I sent it to you." Lu Kang's subordinates cautioned him against taking Yang Hu's medicine because they were worried that Yang Hu might harm him, but Lu Kang ignored them. When the Wu emperor Sun Hao received news of peaceful relations between Wu and Jin, he sent a messenger to reprimand Lu Kang, but Lu Kang replied: "Ordinary peasants in the countryside have to keep their promises, much less me, a government official. If I do not live the virtues, I will appear as a stark contrast to Yang Hu. This does not result in any harm to Yang Hu." However, there were some people who disagreed with the behaviour of Lu Kang and Yang Hu, as they believed that the two men were not fulfilling their loyalties to their respective states.
