 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.For Gao Anagong's betrayal of Gao Wei, Emperor Wu created him a duke and made him the governor of Long Province (隆州, roughly modern Nanchong, Sichuan).
