A major objective of the hukou system implemented by the central government was thus to control the stream of resources moving away from the agricultural sector. The instability and high rates of movement that characterized the years following the establishment of the nation impeded the central government's plan for society and the economy. Although the hukou system in its current form was not officially brought into being until 1958, the years preceding its establishment were characterized by growing efforts by the Chinese Communist Party to assert control over its populace. In 1950, the Minister of Public Security, Luo Reiqing, published a statement detailing his vision for the implementation of the hukou system in the new era. By 1954, rural and urban citizens had been registered with the state, and rigorous regulations on the conversion of hukou status had already been implemented. These required that applicants have paperwork that documented employment, acceptance to a university, or immediate family relations in the city to be eligible. In March of the same year, the Ministry of the Interior and the Ministry of Labor issued the Joint Directive to Control Blind Influx of Peasants into Cities, which proclaimed that henceforth, all employment of rural workers in city firms would be controlled entirely by local labor bureaus.
