he approved of Gao Yan's killing of He Shikai, was still loyal to the emperor, and he intervened on the emperor's side, ordering Gao Yan's troops to disband, and they collapsed. Hulü seized Gao Yan and took him to the palace. At Hulü's urging, Gao Wei spared Gao Yan initially, although in winter 571 he nevertheless executed Gao Yan.
