Tangwai movement
Although the term "Sanmin Zhuyi" (三民主義) has been less explicitly invoked since the mid-1980s, no political party has explicitly attacked its principles with practices under the Martial Law ruling era then except the Tangwai movement groups such as Democratic Progressive Party. The Three Principles of the People remains explicitly part of the platform of the Kuomintang and in the Constitution of the Republic of China.
