To serve the Party is to serve the people.
Mao Zedong

Notes
[1] The Central Social Affairs Department was the predecessor of the Ministry of Public Security. It originated from the Chinese Soviet Political Security Bureau established in November 1931. In November 1935, it arrived in northern Shaanxi with the Red Army during the Long March and was reorganized into the Northwest Political Security Bureau, becoming the primary institution responsible for safeguarding the Central Committee of the Chinese Communist Party, with Zhou Xing, a longtime subordinate of Mao Zedong, serving as its director. In 1937, it was renamed the Border Region Security Office, which served as the public security management department for the Shaanxi-Gansu-Ningxia Border Region, still under Zhou Xing’s charge. Before the establishment of the Central Social Affairs Department, the Border Region Security Office carried out the functions of the Social Affairs Department, and the staff forming the Social Affairs Department and the Intelligence Department were largely transferred from the Border Region Security Office, making the Security Office and the Social Affairs Department derivatives of the same institution. Given the importance of counter-espionage and security work in the border region, Mao Zedong wrote the inscription “To serve the Party is to serve the people” in the internal journal of the Central Social Affairs Department.
