This was the motto of Chang Kuo-sin, and the ideal which he inspired generations of students of communication to follow. He proved his own dedication to this when, in 1949, he found himself in Nanking, the former nationalist capital, under the rule of the newly victorious communists. For eight months he lived and attempted to work in the midst of these historical changes. He managed to smuggle his detailed notes out to share with the world at a time when almost no reports of the new regime were being published. To mark the centenary of his birth, Hong Kong Baptist University’s School of Communication has republished this important work by one of its most distinguished professors.
