as everyone knows , The number and structure of population are important factors affecting social and economic development . Our country has experienced “ Family planning ” To “ Comprehensive two child ”, Until then “ Let go of the three children ” The implementation of the policy , All these are adjustments to the changing trend of China's population development .

Three child policy , China responded positively ageing of population And the implementation of a family planning policy .2021 year 5 month 31 Japan , The Political Bureau of the CPC Central Committee held a meeting , Consideration 《 Decision on optimizing fertility policy and promoting long-term balanced development of population 》 And point out that , In order to further optimize the fertility policy , Implement the policy that a couple can have three children and supporting measures . stay 2022 During the fifth session of the 13th National People's Congress of the people's Republic of China and the fifth session of the 13th National Committee of the Chinese people's Political Consultative Conference in, many deputies to the National People's Congress also issued many “ A good voice ”, Liu Qingfeng, deputy to the National People's Congress, suggested ：“ Implement the policy of encouraging fertility , We should reduce the burden on young people and employers .
