张奂 / Zhang Huan (late Han)
张奂 enters the wiki through Hanji 902 as a late-Han official and frontier figure contrasted with 段熲. The episode says Zhang, Duan, and Huangfu Gui were known together as “Liangzhou Sanming,” but presents Zhang as hostile to eunuch influence while Duan later draws close to it.
Zhang’s immediate danger begins with 王寓. Wang asks Zhang, then taichang, to recommend him; Zhang refuses, and Wang later retaliates by accusing Zhang of belonging to the party-figure network. After Duan becomes sili xiaowei, the episode says Duan considers sending Zhang to Dunhuang and arranging his death en route.
The source’s core use of Zhang is survival-first politics. Zhang writes to Duan in a humbled tone, is spared, returns home, stops seeking office, teaches more than a thousand students, writes more than 300,000 characters, and dies at seventy-eight. The host treats the episode as a case where lowering one’s posture can preserve the future work that pride would have sacrificed.
