《新唐书·列传·卷九十六》
遇上王宰不进兵，宰相李德裕上奏命刘沔镇守河阳，派两千滑州兵在万善扎营，呆在王宰眼皮下，促使王宰出兵。
会王宰逗留，宰相李德裕表沔镇河阳，以滑兵二千壁万善，居宰肘腋下，激之俾出军。
Wang Zai did not advance, and Prime Minister Li Deyu ordered Liu Mian to guard Heyang and sent two thousand Huazhou soldiers to camp at Wanshan, who stayed under Wang Zai's watchful eyes, prompting Wang Zai to send troops.
