Yang Guozhong
Despite their cooperation in posthumously accusing Li Linfu, a rivalry soon developed between An and Yang Guozhong, as An did not fear Yang Guozhong the way he did Li Linfu. Yang Guozhong made repeated accusation against An to Emperor Xuanzong that he was plotting a rebellion, but the accusation were dismissed by Emperor Xuanzong. Yang Guozhong, instead, entered into an alliance with Geshu against An. In spring 754, Yang asserted, to the Emperor, that An was set on rebelling, an accusation Yang had made before. Yang predicted that if Emperor Xuanzong summoned An to Chang'an, he would surely not come. However, when Emperor Xuanzong tested Yang's hypothesis by summoning An, he immediately showed up in Chang'an and claimed that Yang was making false accusations. Thereafter, Emperor Xuanzong refused to believe any suggestions that An was plotting rebellion, despite Li Heng agreeing with Yang's assessment on this issue. The Emperor even considered promoting An to be chancellor; however, Yang opposed this, and the promotion did not occur. An subsequently returned to Fanyang. At An's request, Emperor Xuanzong allowed him to award his soldiers with high ranks without first receiving imperial approval. (Geshu, hearing this, made the same request, and Emperor Xuanzong also granted this privilege to Geshu.) Later in 754, An defeated Xi forces, capturing their chieftain Li Riyue (). Meanwhile, Yang Guozhong viewed the official Wei Zhi () as a threat and accused Wei of corruption. Yang Guozhong later accused Wei of bribing An's associate Ji Wen (), and Wei and Ji were both demoted. An subsequently submitted a petition on their behalf, claiming that the accusations from Yang Guozhong were false, but Emperor Xuanzong took no actions against either An or Yang Guozhong.
