The CC was not a permanent institution. It convened plenary sessions, of which six CC plenary sessions and two joint CC–Central Control Commission (CCC) plenary sessions were held between the 15th Congress and the 16th Congress. When the CC was not in session, decision-making powers were transferred to inner bodies of the CC itself; the Politburo, Secretariat and Orgburo (none of these bodies were permanent either, but convened several times a months).[1]

Apparatus
Individuals employed by Central Committee's bureaus, departments and newspapers made up the apparatus between the 15th Congress and the 16th Congress.[2] The bureaus and departments were supervised by the Secretariat, and each secretary (member of the Secretariat) supervised a specific department.[3] The leaders of departments were officially referred to as Heads, while the titles of bureau leaders varied between chairman, first secretary and secretary.[4]
