《容斋随笔·卷九·朋友之义》
汉唐以来，还有范式和张劭、陈重、雷义、元稹、白居易、刘禹锡、柳宗元这些人，始终交情笃好，不因为死生贵贱而改变他们的心志。
汉、唐以来，犹有范张、陈雷、元白、刘柳之徒，始终相与，不以死生贵贱易其心。
Since the Han and Tang, there have been people such as Fan Shi and Zhang Shao, Chen Zhong, Lei Yi, Yuan Zhen, Bai Juyi, Liu Yuxi, and Liu Zongyuan, who had always been on very good terms with each other and did not change their friendship due to birth or death, positions high or low.
