齐后主
Around the new year 577, Northern Zhou's Emperor Wu led an army intending to lift the siege on Pingyang. Gao Wei engaged him. As soon as the armies engaged, though, Consort Feng misinterpreted a slight backoff by part of the Northern Qi army and panicked, yelling, "We have been defeated!" This caused Gao Wei's official Mu Tipo to panic as well, and together they persuaded Gao Wei to abandon the army. The army collapsed after the emperor left. Gao Wei and Consort Feng then fled north to the secondary capital Jinyang (晉陽, in modern Taiyuan, Shanxi). (Gao Wei had intended to claim, if Pingyang had been captured, that it was the achievement of Consort Feng and then create her "Left Empress," and so had ordered his eunuchs to retrieve ceremonial clothes for an empress from Jinyang; on the way back to Jinyang, they met the eunuch, and despite the defeat, Gao Wei nevertheless had Consort Feng put on the empress's ceremonial clothes, although he did not create her Left Empress as he intended.) Once at Jinyang, Gao Wei had no will to resist Northern Zhou, and he fled back to the capital Yecheng (鄴城, in modern Handan, Hebei) with Consort Feng.
