Unlike the 1951
Zhen Fan campaign (1950–52), which principally targeted those as threats from outside the state system such as former
Kuomintang officials and supporters, the
sufan campaign widened to purge those within the party, military and state agencies who Mao's circle saw as threats. Several top Party officials, notably the technocrats
Gao Gang and
Rao Shushi, were purged in the early stages of the campaign. Many other Party members and government officials were arrested on vague suspicions of counterrevolutionary activity and were made to 'confess' their political views. The
Public Security Bureaus of the
Ministry of Public Security were a particular target, as the communist leadership sought to ensure that China's security forces were under tight Party control. The ''People's Daily'', in an attempt to provide justification for the purge, reported that ten percent of Communist Party members were secret traitors and needed to be purged. This number appears to have been taken as a quota for the number of arrests that needed to occur. There was no judicial process involved; instead, people were targeted through administrative edicts in which regular criminal procedures were ignored. 2.2 million people were reported to have been investigated by September 1955. 110,000 people were purportedly "exposed" as counterrevolutionaries, though Mao continued the campaign for a further two years in the belief that another 50,000 major suspects were still at large. It was effectively a reaction by Mao against the rise of a technocratic bureaucracy dominated by pro-Soviet officials, following the implementation of China's Soviet-inspired
First Five-Year Plan from 1953 onwards. Mao saw the new technocratic ethos in China's administration as a corruption of the "revolutionary spirit". The officials responsible were cast as "functional bourgeoisie" whose power was based on their bureaucratic authority rather than private property. In 1952, he was ordered to Beijing to become head of the
State Planning Commission of China (SPC), where he later attempted a leadership challenge against
Liu Shaoqi and
Zhou Enlai. ==Outcomes==
