周昕 / Zhou Xin (late Han)
周昕 / Zhou Xin (late Han) enters the wiki through Hanji 983 as the figure whose alignment helps explain why 袁术 pushes 吴景 and 孙贲 into 丹阳郡. The source presents Zhou Xin as leaning toward 袁绍, while Yuan Shu and Yuan Shao are hostile.
The page is source-scoped. Zhou Xin is not developed as a biography here; he represents the factional background that turns a commandery appointment into part of the Yuan brothers’ wider competition.
