许历 / Xu Li
许历 / Xu Li enters the wiki through 《资治通鉴·周纪》87丨“狭路相逢勇者胜”终于找到出处了！, where the transcript renders him as 许立. This page keeps the source-scoped variant visible while using the common historical name 许历 for the entity.
In the episode, Xu Li is a Zhao soldier or officer who steps forward after 赵奢 has already moved rapidly toward 阏与 / 燕宇之战. He warns that Zhao’s battle formation needs sufficient depth and that the side which reaches the northern mountain first will dominate the battlefield. Zhao She accepts the counsel, sends ten thousand elite troops to seize the height, and later requests that Xu Li be rewarded.
Xu Li’s function is therefore not independent command but tactical correction. He shows that Zhao She’s strict information control before movement does not mean closed-minded command after contact; once near the field, Zhao She is willing to listen to grounded advice.
