The party lines of the Chinese Communist Party (CCP) shifted frequently over the past century. The success of the CCP in establishing the People's Republic of China (PRC) contributed to the strategy of "encircling the cities from the rural areas," which was developed mainly by Mao Zedong. In order to gain supreme leadership within the CCP, Mao launched the so-called "Rectification Movement" in Yan'an to overcome his political adversaries. After the establishment of the PRC, a series of party line controversies broke out among the CCP leadership over what should be the right way to promote a socialist construct, including, among other things, whether to terminate the New Democracy policy and the struggle between "Rash Advance" and "Opposing Rash Advance." This path accounts for the disaster of the "Great Leap Forward" and prepared the field for the Cultural Revolution. A new round of power struggle broke out after the Cultural Revolution. From the "Reform and Open" policy launched in 1979 through the 20th National Congress of the CCP later this year, the shadow of line disputes and power struggles lingers and reminds us that as a Bolshevik revolutionary party, the CCP's party line and the power of discourse always have to be shifted at the price of fierce power struggles.
