On this day 41 years ago, on April 6, 1984 (March 6, 1984 in the lunar calendar), the resident identity card system came into effect. On April 6, 1984, the State Council issued the "Regulations on the Trial Implementation of Resident Identity Cards of the People's Republic of China", stipulating that: All Chinese citizens living in the People's Republic of China, except those under the age of 16 and active military personnel, armed police, as well as prisoners who are serving sentences and those who are reeducation through labor, shall apply for a resident identity card. Resident identity cards have the legal effect of proving citizenship. Resident identity card registration items include name, gender, ethnicity, date of birth, address and valid period. The valid period of resident identity cards is divided into 10 years, 20 years, and long-term. Implementing the resident identity card system is necessary to maintain social stability and establish a good social order, and it is also an important measure to effectively protect the legitimate rights and interests of citizens. At the same time, it also makes it easier for Chinese citizens to move, go out to work, and better meet the needs of the market economy.
