Taiwan's Ingenious Use of Women's Voices for Secret Messages and Defector Recruitment.

In the 1970s, Taiwanese broadcasters used powerful speakers and shortwave radios to transmit coded messages and propaganda to Communist China, with the female voice, especially that of pop star Teresa Teng, being a key tool for information warfare. The job gave the women a unique viewpoint into cross-strait relations and Taiwan's eventual democratization. Today, their stories gain new relevance at a time of heightened tensions between Taiwan and China.
