《宋史·列传·卷二百三十一》
恰巧蔡卞染上寒病，辽国的接待者受命用白驰车拉他，并说： 你乘坐白驰车，是特殊的礼节了。 出使辽国回来，他以龙图阁待制的身份为宣州知州，转到江宁府，历任扬、广、越、润、陈五州知州。
卞适有寒疾，命载以白驰车，典客者曰： 此，君所乘，盖异礼也。 使还，以龙图阁待制知宣州，徙江宁府，历扬、广、越、润、陈五州。
It happened that Cai Bian contracted a cold, and the Liaos were ordered to pull him with a white chariot, saying: "It is a special courtesy for you to ride in a white chariot." After returning from the mission to Liao, he served as the Governor of Xuanzhou as the Deputy Minister of Longtu Pavilion, transferred to Jiangning Mansion, and successively served as the Governor of Yangzhou, Guangzhao, Yueyang, Runzhou, and Chenyang.
