Bo Gu
Before long, with the arrest of Gu ShunZhang (), who was in charge of security for the CPC, many senior leaders such as Xiang and Yun Daiying () were arrested and executed. Wang returned to Moscow with his wife with a medical excuse. After Wang's departure, under the direction of Zhou Enlai, an acting politburo was set up in Shanghai. Zhou, Zhang Wentian, Bo Gu, Kang Sheng, Chen Yun, and Lu Futan (), Li Zhusheng () were selected to be in charge of the daily work of the CPC. Among these people, Zhang, Bo Gu and Li were members of the 28 Bolsheviks and close associates of Wang, so Wang could still keep remote control over the CPC through his associates. Furthermore, Kang and Chen met him and became his supporters in Moscow several years later. Both Lu and Li would later defect to the KMT.
