黨外運動
During the 1970s, Lu established herself as a prominent feminist advocate in Taiwan, which included writing of "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 "tang-wai", the opposition movement calling for democracy and an end to authoritarian rule.
