《旧唐书·列传·卷一百四十》
兄长隐居沉沦下位，不被收录任用，豫让所以不报答范氏中行氏，那是因为他们只以对待一般人态度来对待豫让。
兄遁迹下僚，不被收用，豫让所以不报范中行，只以众人遇我者也。
Brother has lived in seclusion and sunk to a low position, and was not accepted or employed. Yu Rang therefore did not repay the Fan clan and Zhongxing clan, because they only treated Yu Rang with the same attitude as they treated ordinary people.
