《资治通鉴·唐纪·唐纪四十三》
孟华来到恒州时，王武俊的军队已经开拔。孟华规劝王武俊说： 圣上对大夫很是寄以厚望，如果能够竭尽忠义，何愁官职爵位不高、土地不广呢！不久皇上肯定会将康中丞改迁到其它军镇去，深州、赵州终究属于大夫，何苦骤然间将自己置身于叛逆之列呢！将来不能成功，后悔也来不及了。 
华至，武俊已出师，华谏曰： 圣意于大夫甚厚，苟尽忠义，何患官爵之不崇，土地之不广，不日天子必移康中丞于它镇，深、赵终为大夫之有，何苦遽自同于逆乱乎！异日无成，悔之何及！ 
When Meng Hua arrived in Hengzhou, Wang Wujun's army had already set off. Meng Hua tried to persuade Wang Wujun, saying: The emperor has high hopes for you, if you can do your best to be loyal and righteous, why worry about not having a high official position, a noble title, or a large piece of land! Soon the emperor will definitely transfer Commander Kang to another military town. In the end, Shenzhou and Zhao will still belong to you. Why bother to put yourself in the position of a rebel all of a sudden! If you don't succeed in the future, it will be too late to regret it.
