On October 30, 2015, the Fifth Plenary Session of the 18th National Congress of the Communist Party of China passed and announced that mainland China will fully implement the two-child policy, which is of great significance to China\’s current actual national conditions. We can promote balanced population development, improve the population development strategy, fully implement the policy that a couple can have two children, and actively carry out actions to deal with the aging of the population. Although many people are happy for the opening of the second-child policy, many people lack a real understanding of the second-child policy and cannot clarify the pros and cons of the second-child policy.
