Чжан Чуньцяо
Factional rivalries intensified at the Second Plenum of the Ninth Congress in Lushan held in late August 1970. Chen Boda, now aligned with the PLA faction loyal to Lin, galvanized support for the restoration of the office of President of China, despite Mao's wishes to the contrary. Moreover, Chen launched an assault on Zhang Chunqiao, a staunch Maoist who embodied the chaos of the Cultural Revolution, over the evaluation of Mao's legacy.
