娄昌 / Lou Chang
娄昌 / Lou Chang enters the wiki through 《资治通鉴·周纪》94丨杀神白起，长平之战中的“草包”名将？（1） as the 赵国 adviser who recommends sending an important envoy to 秦国 to seek peace during the 长平之战 prelude. His advice is the option 赵丹 / 赵孝成王 effectively follows when he sends 郑朱 to 咸阳.
The episode uses Lou Chang mainly as a foil for 虞卿. Lou Chang’s direct-peace approach treats negotiation as the immediate escape from battlefield pressure, while Yu Qing argues that negotiation without restored alliance leverage only broadcasts weakness.
