焦邑 / Jiaoyi

焦邑 / Jiaoyi appears in 《资治通鉴·周纪》34丨秦国总理如何玩转六国 as one of the two 魏国 strongholds 秦国 pressures after Wei has already ceded 殷晋. Qin surrounds Jiaoyi and 曲沃 in 330 BCE, and the episode says Jiaoyi is eventually taken in 329 BCE.

The source keeps Jiaoyi important through its later return. After Qin has gained from repeated coercion and from 张仪’s 蒲阳 maneuver, it returns Jiaoyi and Quwo to Wei, making the place part of the episode’s closing puzzle about why Qin sometimes gives back captured territory.
