Chen Boda
Kang Sheng was instrumental in supervising the drafting of the new Party Constitution, adopted at the CPC's Ninth Congress in April 1969, which reinstated "Mao Zedong Thought" alongside Marxism-Leninism as the theoretical basis for the Party. The Congress elected Kang as one of the five members of the Politburo Standing Committee, along with Mao, Lin Biao, Zhou Enlai and Chen Boda. At the Ninth Congress, Kang Sheng's wife, Cao Yi'ou, was herself elected to the Central Committee.
