Chen Lifu
He rapidly rose within the Kuomintang hierarchy with the support of the so-called "Central Club Clique" led by Chen Lifu and by 1934 chaired the Research and Statistics Department, which was a cover for the Kuomintang secret police. However, when forced out of power due to numerous corruption scandals in a reorganization of the Kuomintang in 1938, he defected to the Japanese side along with Li Shiqun. Under the direction of Japanese spymaster Kenji Doihara, the two worked to create an intelligence and secret police security service, which was founded in April 1939 and whose headquarters was located at 76 Jessfield Road in Shanghai. This address contained holding cells, where suspected Communists and Kuomintang prisoners could be interrogated and executed.
