于定国 / Yu Dingguo

Overview

于定国 / Yu Dingguo enters the wiki through Hanji 524 as the father of 于永 and a Western Han senior official whose career background helps explain Yu Yong’s prestige.

Current Profile

The episode gives Yu Dingguo as a high-status predecessor rather than a full biography. It says he replaces Huang Ba as chancellor, is enfeoffed as Xiping Hou, remains respected after Han Yuan’s accession, and is later allowed to retire with carriage, horses, and gold. He dies in his seventies, and the episode treats that end as relatively fortunate.
