The sentence "The Wei family was completely destroyed" in "Hanshu: Biography of Wife's Wife" refers to the "annihilation" of the Wei family's power in the court, not that the entire Wei family was destroyed.

In later generations, there were also people who were granted the title of marquis and became officials.
