楚怀王 / King Huai of Chu
楚怀王 / King Huai of Chu appears in 《资治通鉴·周纪》34丨秦国总理如何玩转六国 through the 329 BCE succession notice. 楚威王 dies, and his son succeeds as the new ruler of 楚国.
The source treats the notice as a preview rather than a developed biography. It says Chu Huai Wang will become one of the more dramatic rulers in Warring States history and notes that the Qu Yuan-era narrative is approaching, but this episode keeps him mainly as a marker that the political map is widening beyond the Qin-Wei front.
