《资治通鉴·唐纪·唐纪六十六》
唐懿宗咸到奇怪，遣使问李维周，李维周上奏唐懿宗称高骈驻军于峰州，与南诏蛮军周旋，不敢进兵。
上怪之，以问维周，维周奏骈驻军峰州，玩寇不进。
Emperor Yizong of Tang became suspicious and sent an envoy to ask Li Weizhou, and Li Weizhou stated in his report to Emperor Yizong that Gao Pian had since resided with his army in Fengzhou, engaging in battles with the Nanzhao barbarians and not daring to advance.
