蔡元培做北京大学校长时,有一天,一名北大毕业生去见他,不知道为了什么,冲着他大吵大闹后离去。第二天,这名毕业生拿着一张求职表格,又去见蔡元培,要求他写封推荐信。蔡元培看看他所填的表格,马上就为他写了推荐信。事后,傅斯年问蔡元培:“这个学生昨天还冲着你大吵大闹,为何今天你肯为他写推荐信?” When Cai Yuanpei was the president of Peking University, one day a Peking University graduate went to see him and did not know what was going for him and left for his quarrel. The next day, the graduate took a job application form and went to see Cai Yuanpei, asking him to write a letter of recommendation. Cai Yuanpei to see the form he filled in, and immediately wrote a letter of recommendation for him. Afterwards, Fu Ssunese asked Cai Yuanpei: “This student was still yelling at you yesterday, why today you are willing to write a letter of recommendation for him?”
