阏氏 / Ezhi (Warring States)
阏氏 / Ezhi appears in 《资治通鉴·周纪》65丨我穿越去给浪漫的楚王念首诗 as the place reached by the five-state anti-Qin coalition in 296 BCE. The episode names Qi, Han, Wei, Zhao, and Song as the attacking states.
Ezhi’s wiki role is to mark the point at which coalition pressure becomes strong enough for 秦国 to seek accommodation. Qin returns 武遂 to 韩国 and 封陵 to 魏国, turning the battlefield notice into a case of strategic concession diplomacy and hezong fragility.
