《后汉书·列传·卓鲁魏刘列传》
当时鲁恭才十二岁，其弟鲁丕才七岁，兄弟日夜号哭跳跃不绝于声，郡中赠送的丧仪财物都不接受，于是回家服丧，礼节比成人还要周到，乡里深感奇异。
时恭年十二，弟丕七岁，昼夜号踊不绝声，郡中赙赠无所受，乃归服丧，礼过成人，乡里奇之。
Ru Gong was only twelve at that time, and his younger brother Ru Pi was only seven years old, the two brothers wept and shouted day and night, and refused to accept the funeral supplies given by the county, and returned home to observe the mourning period, and their etiquette was even more thoughtful than that of adults, which amazed the local people.
