"The Communist Party of China, as a Marxist political party, has regarded the preservation of the Party’s purity as a fundamental principle and important goal of Party building throughout the course of China’s revolution, development, and reform. Many years ago, Mao Zedong made it clear that the Party was to be “a well-disciplined party, pure in its thought and ranks, and conforming to a single unified standard.” The purity of the Party is manifested ideologically, politically, organizationally, and in styles of work."
