George Chang. George Chang or Chang Tsan-hung (; born 1 March 1936) is a Taiwanese politician, chemical engineer, and independence activist. He was the mayor of Tainan City from 1997 to 2001.

Early life and education 
After graduating from the National Tainan First Senior High School, Chang attended National Taiwan University to study chemical engineering. In 1961, Chang arrived at the United States to study at Rice University, where he got his doctorate degree. He taught chemical engineering as a professor at Cooper Union.

During his stay in the US, Chang started taking part in the Taiwan independence movement. He was the first vice chairperson of the World United Formosans for Independence (WUFI), and became its chairperson in 1973. During the occurrence of the Kaohsiung Incident, Chang also advocated many Taiwanese Americans to support the democratic movement going on in Taiwan.

In 1991, Chang returned to Taiwan. In the same year, he was indicted for "leading a rebellion" (首謀內亂罪). However, because of the amendment of "Crime Law Article 100" (刑法第100條), he was pleaded not guilty in October 1992. He later joined the Democratic Progressive Party (DPP) and was nominated by the party to run for legislator. However, he was not elected as he only got thirty thousand votes. In 1997, he was nominated by the DPP to run for the mayor of Tainan and was elected with over one hundred thousand. He became the first mayor of Tainan to be a member of the DPP.
