张开地 / Zhang Kaidi

张开地 / Zhang Kaidi appears in 《资治通鉴·周纪》26丨孟子来了！ as the 韩国 chief minister who succeeds 申不害 after Shen’s death in 337 BCE. The episode uses him less for a standalone biography than for the continuity of one Han-serving family across several rulers.

His importance is retrospective. Because Zhang Kaidi is presented as 张良’s grandfather and 张平’s father, the source reads Zhang Liang’s later anti-Qin and pro-Han action as rooted in family-political memory rather than only personal grievance.
