《新唐书·列传·卷三十八》
他以仁爱治理政务，不忍心使用体罚，百姓感激他的恩德，递相约定说： 谁在徐参军任上犯杖刑以上的罪行，我们就一定要斥责他。 
为政仁，不忍杖罚，民服其恩，更相约曰： 犯徐参军杖者，必斥之。 
He governed with benevolence and was reluctant to use physical punishment; the people were grateful for his benevolence and secretly agreed, "Whoever commits a crime punishable by flogging during Xu the Honorable's term of office, we are bound to reproach him."
