During the 1970s, Lu established herself as a prominent
feminist advocate in Taiwan, which included writing for
New Feminism or
Xin Nüxing Zhuyi (). She renounced her KMT membership, joined the
tangwai movement, and worked on the staff of
Formosa Magazine. Lu then became increasingly active in the movement, calling for democracy and an end to authoritarian rule. In 1979, Lu delivered a 20-minute speech criticizing the government at an
International Human Rights Day rally that later became known as the
Kaohsiung Incident. Following this rally, virtually the entire leadership of Taiwan's democracy movement, including Lu, was imprisoned. She was tried, found guilty of violent sedition, and sentenced by a military court to 12 years in prison. She was named by
Amnesty International as a
prisoner of conscience, and, due to international pressure, coupled with the work of
Ma Ying-jeou and
Jerome A. Cohen, was released in 1985, after approximately five and a half years in jail. In the 1990s, Lu worked to have Taiwan reenter the United Nations, not under the name "Republic of China" but as "Taiwan".
Elected offices Lu joined the
Democratic Progressive Party in November 1990, and was elected to the
Legislative Yuan in 1992. In 1997, she won an election to be the
Magistrate of her hometown of
Taoyuan, a post she held until Chen Shui-bian selected her as his running mate in the 2000 presidential elections. ==Novel==
