Due to Mao Zedong's support, the RCMS saw its rapidest expansion during Cultural Revolution, reaching a peak of covering 85% of the total population in 1976. However, as a result of agricultural sector reform and end of People's Commune in the 1980s, the RCMS lost its economic and organizational basis. Therefore, RCMS collapsed, with only 9.6% coverage in 1984.[10][11]
