Chapter 4 details the encroachment of the government’s silencing machine on Hong Kong citizens’ daily lives at the height of the Cold War. The period from the 1950s to the 1960s saw CCP cultural infiltration into various sectors of Hong Kong in an attempt to propagate anti-colonial patriotic ideas and communist ideologies. The CCP not only published, directly or indirectly, newspapers, books and magazines in Hong Kong, but also sponsored schools and film studios and staged theatrical performances. Together with the co-existence of KMT supporters and intelligence agents of other world powers in the colony, Hong Kong became an important ideological battleground of the Cold War in Asia. The colonial government responded by hardening its monitoring of newspapers and schools, suppressing them when necessary. It also monopolised the preparation of news bulletins for radio broadcasting and imposed political censorship on radio entertainment programmes, films and theatrical performances. Radical movements of the KMT and CCP also led to the two most violent riots in colonial Hong Kong history, in 1956 and 1967, respectively, in which a large number of political dissidents were deported, detained without trial and imprisoned for speech offences.
