"The secret of Mao’s success at Yan’an was his flexibility at combining short-term and long-term goals. In the short term he espoused in 1940 the New Democracy as a united-front doctrine that would embrace all the Chinese people who would subscribe to CCP leadership. For the long term, he steadily developed the party organization, including its control over intellectuals. The Yan’an rectification movement of 1942–1944 (more fully described below) established the campaign style of mobilization, including individual isolation, terror, struggle, confession, humiliation, and subservience. Party members would come to know it well and, in time, so would the public. It was one of Mao’s achievements, with roots both in Leninism–Stalinism and in Imperial Confucianism."
