张献 / Zhang Xian (late Han)
张献 / Zhang Xian enters the wiki through Hanji 1027 as the Changsha administrator who becomes the southern pressure point against 刘表. The episode describes him as a hard-edged local official from a Nanyang great family, with enough local support to make resistance politically meaningful rather than merely personal.
Under 桓阶’s advice, Zhang Xian joins 长沙郡, 零陵郡, and 桂阳郡 into a southern Jingzhou alignment against Liu Biao and submits to 曹操. Cao Cao then uses court authority to recognize him as Zhengnan general, turning a local commandery dispute into a strategic constraint that keeps Liu Biao from easily aiding 袁绍.
