Since 1949, when communist took over Mainland China, Taiwan and Hong Kong became the shelters of many scholars. They kept in touch with one another through mails. This essay focuses on this postal communications between Prof. Maurus Fang Hao (方豪) and some scholars in Hong Kong, such as Lo Hsiang-Lin ( 羅香林 ) , Mo Ruan-Sun ( 牟潤孫 ) , and Catholic Bishop Francis Hsu ( 徐誠斌 ) . And it is found that, (1) Fang provided some historical data or gave advices to their essays; and (2) Fang joined the committee on Master or Doctor Degree of University of Hong Kong and Chu Hai College. As the first generation of scholars who emigrated to Taiwan and Hong Kong in 1950's, have been fading away gradually, this essay pays respect to them in offering only a specific facet of this special period.
