《资治通鉴·汉纪·汉纪十七》
张安世曾向朝廷举荐过一个人，此人前来道谢，张安世非常生气，认为： 为国家举荐贤能，难道可以私相酬谢吗！ 
尝有所荐，其人来谢，安世大恨，以为 举贤达能，岂有私谢邪！ 
Zhang Anshi once recommended someone to the court. The person came to thank him, but Zhang Anshi was very angry. He believed that "it is not possible to pay private favors for recommending talented people to the country."
