File photo shows fishermen of Nushan Lake Fishery Commune vote for deputies in Jiashan County, east China's Anhui Province, in 1981. The Electoral Law was enacted in 1953 and completely revised in 1979. It then underwent four minor amendments. The electoral system is the foot stone of democracy, and the principle of equality is a prerequisite to guarantee people's democratic rights. The amendments of electoral law can be seen as records of the development of democracy in China.
