Wang Yu-chi
Few days later on 21 August 2014, Chang held a press conference in Taipei responding to an allegation he received from the government that he had leaked national secrets to Mainland China thus that he was actually sacked from the MAC by Minister Wang Yu-chi. During the press conference, Chang said that he called on President Ma Ying-jeou to take care for himself because Ma had been 'hijacked' by a handful of people and deceived into believing allegations against him were fabricated by those people.
