中山国 / Zhongshan State

中山国 / Zhongshan State appears in Zhouji 09 as a state that had been conquered by 魏国 under Wei Wenhou but revives during the later melee. The source says Wei Wuhou’s brother 魏挚 had been guarding the area, which was a detached territory separated from Wei proper by 赵国.

The episode uses Zhongshan to show how frontier control can reverse quickly when the main powers are distracted. After Di forces drive out Wei Zhi, Zhongshan revives but still continues relations with Wei and aligns with Wei against Zhao, making it a compact case of early Warring States pragmatism.
