Zhou Enlai: From the Anti-Japanese War to the Anti-Japanese War, his ambition was the national revolution; from the May Fourth Movement to the Human Rights League, his journey was to democracy and freedom.

Mao Zedong: An academic leader and a role model in the world.

Wang Yuanfang: Cai Yuanpei is the only figure in our country who is respectful in appearance and gentle in speech.

Shou Zhulin: The pure and profound knowledge and morality of the people, peace and righteousness, but the world is full of troubles, just as Zhuangzi said, pure and often, it is better than the crazy. The moral knowledge of Jiemin is a collection of great achievements from ancient and modern times, both at home and abroad, and it can be said to be great if it is put into practice and is magnanimous without choosing the right one to follow and not being ashamed to ask questions from below.

Feng Youlan: Cai Yuanpei is a person who truly meets the standards of a gentleman in modern times. Mr. Cai’s personality is the highest expression of Confucian educational ideals.

Fu Sinian: Mr. Cai Yuanpei actually represents two great cultures: one is the cultivation of traditional Chinese sages; the other is the Western European ideal of freedom and fraternity. One of these two cultures is difficult, but having both is particularly difficult. After the death of Mr. Wang, these two cultures have become extinct in China!

Chen Duxiu: Generally speaking, Mr. Cai is a good old man who does everything he can. However, sometimes when it comes to important matters or things he has made up his mind, he stubbornly persists and cannot do anything. Accommodating, although his attitude is still very gentle; this is the first admirable thing about this old man. Since the 1898 Coup, Mr. Cai himself has often been inclined to the new progressive movement. However, when he was the president of Peking University, he regarded the conservative Chen Hanzhang, Huang Pei, and even Gu Hongming, who advocated the restoration of the Qing emperor, and Liu Shipei, who participated in the Hongxian Movement, because of their intellectual The insight of being able to be a teacher while respecting the freedom of academic thought is rare among the Orientals who are accustomed to autocracy and like common denominators and dislike dissenters. This is the second more admirable point of this old man.

Dewey (famous American educator): Compared with the principals of top schools such as Oxford, Cambridge, Harvard, and Columbia, Cai cannot compare with them in professional knowledge; but in education, they cannot compare with Cai. As a president, apart from Cai Yuanpei, I am afraid there is no other person who can lead that university and play a turning role in a nation and an era.

Lin Yutang: Mr. Cai (Yuanpei) is Mr. Cai. This is the common feeling among Peking University colleagues. The meaning of "blind" seems to contain infinite love and respect, and it also seems to say that there is no second Mr. Cai in the world. Although others have their strengths and weaknesses, everyone agrees that there is nothing more to say about Mr. Cai.
