齐后主
With Northern Zhou forces approaching Yecheng, Gao Wei abandoned Yecheng as well and fled south of the Yellow River, intending to try to regroup and make one final stand, and flee to Chen Dynasty if he failed. He initially fled to Ji Province (濟州, roughly modern Liaocheng, Shandong), but then headed further to Qing Province (青州, roughly modern Qingzhou, Shandong). He left Gao Anagong in charge of defending Ji Province and notifying him as to Northern Zhou's advances. However, Gao Anagong made a secret offer to betray Gao Wei, and he sent false information to Gao Wei, making Gao Wei believing that Northern Zhou forces were not advancing quickly. When Northern Zhou forces arrived at Ji Province, Gao Anagong surrendered and directed them toward Qing Province, and they were able to capture Gao Wei with relative ease.
