of age, the Duke of Zhou dutifully gave up the throne without trouble. Legacy The duke's eight sons all received land from the king. The eldest son received Lu; the second succeeded to his father's fief, Zhou. In later centuries, subsequent emperors considered the Duke of Zhou a paragon of virtue and honored him with posthumous names. The empress Wu Zetian named her short-lived 8th-century Second Zhou Dynasty after him and called him the Honorable and Virtuous King (, Bāodé Wáng).

The genealogy is found in the Mencius family tree ().
