 By 572, both Zu and Mu were in dispute with Hulü—Zu over several instances where Hulü believed that Zu disrespected him and making disparaging remarks about Zu's being blind, and Mu over Hulü's refusal to allow him to marry one of Hulü's daughters by a concubine and Hulü's opposition to Gao Wei's granting of some public fields to Mu.That year, Zu falsely accused Hulü of treason, and Gao Wei executed Hulü and massacred almost all members of his clan.
