伶征 / Ling Zheng (late Han)
伶征 / Ling Zheng enters the wiki through Hanji 929 as the protector of the Qiang killed when 先零羌 and associated rebel groups rise in the western frontier. The source names his death before 北宫伯玉 and 李文侯 become rebel commanders.
The page is source-scoped. Ling Zheng’s significance here is structural: his killing marks the breakdown of the formal Qiang-management office before 边章 and 韩遂 are coerced into the rebel command field.
