曹仁 / Cao Ren
曹仁 / Cao Ren enters the wiki through Hanji 974 as part of the source’s retrospective explanation of how 曹操 adjusts after 张邈 and 陈宫 betray him in 兖州. The episode says Cao Cao later strengthens clan control of core military power, naming Cao Ren alongside 夏侯惇 as trusted kin-commanders.
The page is source-scoped. Hanji 974 does not narrate Cao Ren’s campaigns; it uses him as a personnel-architecture marker in Cao Cao’s post-crisis move toward broader recruitment plus tighter control over decisive armed force.
