吴国桢曾任国民党中央党部宣传部长,去台湾后任台湾省政府主席兼保安司令,后因与蒋介石政见不合辞职去了美国。1923年,年仅20岁的吴国桢申请美国普林斯顿大学哲学博士。当他去面试时,教务长看他一脸孩子气,说:“年轻人,你还没有成熟啊。”吴国桢当即回答说:“先生,依照年龄来判断一个人是否成熟,本身就是一种不成熟啊。” Wu Guozhen served as propaganda minister of the KMT Central Party Department, went to Taiwan as the chairman and security chief of the Taiwan Provincial Government, and later went to the United States for resigning from Chiang Kai-shek’s political opinion. In 1923, only 20-year-old Wu Guozhen applied for a PhD in philosophy at Princeton University. When he went to the interview, the dean saw him look childish, said: “Young people, you have not yet matured ah.” Wu Guozhen immediately replied: “Sir, in accordance with the age to determine whether a person is mature, itself is a Immature ah. ”
