晋阳 / Jinyang
晋阳 / Jinyang enters the wiki through Hanji 155-2 as the place 韩信 occupies after defeating the Dai forces around 阏与. The episode treats Jinyang as the immediate administrative hinge for setting up 太原郡.
Jinyang matters because the northern campaign is not only a raid. Once Han Xin takes the place, the Han side can convert the victory into a commandery base while continuing toward the Zhao-front problem involving 张耳, 陈馀, and 赵歇.
