He graduated from the Department of Transportation and Logistics Management at National Chiao Tung University with a doctorate and served as station master at Taipei Main Station from 1987 to 1991.[1] Chang later successively assumed several public service posts relating to public transportation and tourism.[2] Such positions included leading the tourism division of the Taipei Economic and Cultural Office in New York,[3][4] a stint as director of the Southwest Coast National Scenic Area,[5] and within Tainan City Government as municipal Bureau of Transportation director and the city's deputy mayor under William Lai.[2][6]
Chang became political deputy minister of transportation and communications after Lai assumed the premiership. As a result of the derailment of a Puyuma express train in October 2018, Taiwan Railways Administration Director-General Lu Chieh-shen resigned.[7] Chang was appointed to the TRA on 25 October and stepped down at the Ministry of Transportation and Communications to succeed Lu.[8] Chang began his tenure as TRA director-general on 9 November 2018.[9]
