《新唐书·列传·卷一百一十三》
张颢气得一甩袖子走了，大家于是一起对李俨请求，按皇帝的命令任命杨渥兼任侍中、淮南节度副大使、东面诸道行营都统，封爵弘农郡王。
颢投袂去，乃共请于俨，承制授渥兼侍中、淮南节度副大使、东面诸道行营都统，封弘农郡王。
Zhang Hao left in a huff, and everyone asked Li Yan to appoint Yang Wo as the concurrent Official-in-Waiting, Deputy Governor of Huainan, and Commander of the Eastern Route Army according to the emperor's order, and to confer upon him the title of King of Hongnong.
