In late 1963, the University Distinctive Marks and Ceremonial Dress Committee invited the Departments of Chinese Literature of three Foundation Colleges to contribute ideas for the Chinese University's motto. The committee agreed to use 'Po Wen Yueh Li' (Through Learning and Temperance to Virtue), which was proposed by New Asia College, as the University's motto on 17 January 1964.

'Po Wen Yueh Li' is considered to be emblematic of the teachings of Confucius. According to the Analects of Confucius, Confucius says, 'The superior man, extensively studying all learning, and keeping himself under the restraint of the rules of propriety, may thus likewise not overstep what is right.' (James Legge's translation) New Asia College's proposal letter says that 'Po Wen Yueh Li' is parallel in structure and harmonious in tone. Moreover, it is a fitting motto for CUHK as it reflects the University's vision of placing emphasis on both the intellectual and moral aspects of education.

Written by Mr. Pan Chung-kwei, head of its Department of Chinese Literature, the proposal letter is now on display in the University Gallery.
