武夏 / Wu Xia
武夏 / Wu Xia appears in the 《战国策》 supplement summarized by 《资治通鉴·周纪》36丨卫嗣君的帝王之术. A 卫国 envoy has served 魏惠王 / 梁惠王 for three years without receiving an audience, then uses heavy payment to ask Wu Xia for help.
Wu Xia does not directly demand that Wei Hui Wang receive the envoy. Instead, he begins from what matters to Wei: the possibility of 秦国 pressure and the need to maintain relations with Qin. He then turns the analogy back on Wei Hui Wang, saying that people are urgent when others work for them but slow when they must work for others; if Wei neglects someone serving Wei, how much more likely is it to neglect voluntary work for Qin?
The episode uses Wu Xia as a case of diplomatic reframing. A low-status Wey request becomes visible only when tied to a high-priority Qin relationship, making the story adjacent to low-posture statecraft without being the same as deliberate weakness.
