《宋史·列传·卷二百三十》
韩绛为陕西宣抚使，看到他写的乐语，认为他是人才，就推荐给他的弟弟开封尹韩维，让蔡确任管干右厢公事，韩维离开后蔡确才到任。按规定属吏应在公庭谒见长官，蔡确不肯，接任的开封尹刘庠责问他，蔡确说： 唐代藩镇自设僚属，才有这个礼节；现在我们都侍奉皇上，是同僚，即使是旧的规定也可不用。 就请求解除官职。
第进士，调邠州司理参军，以贿闻。转运使薛向行部，欲按治，见其仪观秀伟，召与语，奇之，更加延誉。韩绛宣抚陕西，见所制乐语，以为材，荐于弟开封尹维，辟管干右厢公事，维去而确至。旧制当庭参，确不肯，后尹刘庠责之，确曰： 唐藩镇自置掾属，故有是礼。今辇毂下比肩事主，虽故事不可用。 遂乞解职。
Han Jiang was the pacification envoy for Shaanxi. After reading the music piece he wrote, he considered him a talented person, so he recommended him to his younger brother, the magistrate of Kaifeng, Han Wei, who appointed him as the official in charge of the right wing affairs of the civil service. Cai Que did not take up his position until Han Wei left. According to the regulations, the subordinates should pay a visit to their superiors in the court, but Cai Que refused to do so. Liu Xiang, the magistrate of Kaifeng who took over, questioned him. Cai Que said: the vassals in the Tang Dynasty set up their own subordinates and they followed this etiquette; now we all serve the Emperor and we are colleagues, so even the old regulations can be ignored. He then asked to be relieved of his official position.
