In preparation for the Eighth National Congress, held in September 1956, Peng attended a Politburo committee to redraft the new Party Constitution. At the meeting, Peng suggested for a section in the Constitution's preamble referring to Mao Zedong Thought to be removed. Liu Shaoqi, Deng Xiaoping, Peng Zhen, and most other senior CPC members present quickly agreed, and it was removed from the final version of the 1956 Party Constitution. At the Congress, Peng was reappointed to the Politburo and as a full member of the Central Committee.
