美麗島事件
Preparations for the assassination of Liu started in July 1984, according to the tape-recorded confession of Chen Chi-li, leader of the Bamboo Union Triad. Earlier, in the wake of the 1979 Kaohsiung Incident, Chen had reorganized the Bamboo Union to assist the Kuomintang-led government in gathering information and suppressing dissidents. In July 1984, Chen and an unnamed "prominent Taiwan movie producer" received espionage training after being inducted into the service of military intelligence.
