Yang Hu
The "Jin Yang Qiu" () recorded that Lu Kang was on friendly terms with the Jin general Yang Hu even though they stood on opposing sides. Their friendship was likened to that of Zichan and Jizha during the Spring and Autumn period. Lu Kang once sent wine to Yang Hu, who drank it without showing any signs of suspicion. Later, when Lu Kang fell sick, Yang Hu sent medicine to him, which Lu Kang also took without suspecting anything. The people of that time remarked that the relationship between Lu Kang and Yang Hu was like that of Hua Yuan and Zifan during the Spring and Autumn period.
