《北史·本记·卷七》
太后答应后，才停止打后背，改成打脚五十次，两脚都打遍了，这才穿好衣服，整好头上的帽子，向太后跪拜谢罪，伤心得难以自制。这次事情过后，他便戒了酒。
太后听许，方舍背杖，笞脚五十，莫不至到。衣冠拜谢，悲不自胜，因此戒酒。
Only when the empress dowager agreed did he stop beating his back and switched to beating his feet fifty times. He only got dressed after receiving punishment on both feet. He then straightened his hat, knelt before the empress dowager to apologize and was so sad he could not control himself. After this incident, he stopped drinking.
