In the early days of the Cultural Revolution, the Politburo Standing Committee ceased normal operations, as many of its key members, such as Liu Shaoqi and Deng Xiaoping, fell out of favour with Mao. Real power was concentrated in the Cultural Revolution Group, which was nominally reporting to the Politburo Standing Committee but in fact was a separate "centre of authority" that acted mostly on its own accord. At the 9th National Congress of the Chinese Communist Party, radical supporters of Mao, Chen Boda, and Kang Sheng, gained seats on the Politburo Standing Committee, and it resumed a somewhat normal functioning. The last years of the Cultural Revolution were dominated by internal chaos. Between 1975 and 1976, PSC members Kang Sheng, Zhou Enlai, Zhu De, and Mao all died. Deng Xiaoping was purged. During this time the body lost any semblance of a functioning policy-making or executive organ, and it met only on an ad hoc basis. By Mao's death in September 1976, the only members who still attended meetings were Hua Guofeng, Zhang Chunqiao, Wang Hongwen, and Ye Jianying, with Zhang and Wang being members of the Gang of Four. On 6 October, Hua Guofeng called a PSC meeting ostensibly to discuss Mao's legacy and memorial arrangements, inviting the active PSC members to attend. Wang and Zhang were both arrested at the meeting and accused of "counter-revolutionary crimes". Thereafter, only Ye and Hua continued their official duties. A functioning PSC was not restored until 1977.
