In April 2019, Chang Chih-lun contested the
Kuomintang party primary for the
2020 legislative election. He was seeking the
New Taipei 8 seat in the
Legislative Yuan once held by his father. He lost that contest, and was placed on the proportional party list instead. When the list was first announced, Chang was ranked in the 27th position. When the list was finalized, Chang was listed 26th. The Kuomintang won 33.36% of the party list vote, enabling thirteen legislators to take office; Chang was not seated to the Legislative Yuan. In March 2020, Chang was elected head of the Kuomintang branch office in
Zhonghe. Chang received KMT support to run in the
2024 election and faced
Democratic Progressive Party candidate Justin Wu and
Taiwan People's Party candidate
Andy Chiu. Chang was elected to the Legislative Yuan in his second bid for the office. ==References==
