Mu Tipo
Emperor Wu initially treated Gao Wei with honor and created him the Duke of Wen, taking Gao Wei and the Gao clan members back to the Northern Zhou capital Chang'an with him. However, in winter 577, apprehensive about the Gao clan, Emperor Wu falsely accused Gao Wei and Mu Tipo of conspiring. He put Mu to death and forced Gao Wei and the other Gao clan members to commit suicide.
