韩景侯 / Marquis Jing of Han
《资治通鉴·周纪》04｜豫让 为智瑶复仇 adds Han Jinghou’s formal-recognition role. The episode identifies him as Han Qian, one of the Jin grandees whom 周威烈王 appoints as a vassal ruler in the opening 《资治通鉴》 notice.
韩景侯 / Marquis Jing of Han appears in 《资治通鉴·周纪》07丨两起刺杀（1） as the 韩国 ruler whose death in 400 BCE is followed by 韩烈侯’s accession. The episode uses the timing to explain why 郑国 may have attacked Han-held Yangdi during a vulnerable mourning and succession window.
《资治通鉴·周纪》10丨 以家族单位 有蚂蚁吃大象的精神（1） looks back to Han Jinghou as a key relay point in Han’s multi-generation strategy against Zheng. The source says he accepted 周威烈王’s recognition as a vassal and moved the Han capital to Yangdi, continuing the direction set by 韩康子 and 韩武子.
