如今，中国正步入老龄化社会，因此独生子女一代面临着巨大的工作和生活压力。中国政府开始适当调整计划生育政策，允许一些家庭在特殊情况下生育二胎。但调查显示，很多夫妻迫于不断加重的经济压力，放弃生育二胎。因此，要从根本上解决老龄化的问题不能依靠出生率的上升，最有效的办法是建立有效的社会保障制度。
Nowadays, China is stepping into the aging society. Therefore, the only-child generation is facing enormous pressure both from work and life. The Chinese government has begun to adjust the familyplanning policy and allows some families to have a second child under certain circumstances. However, the survey shows thatsome couples abandon to have a second child due to the increasing financial burden. Thus, in order to solve the aging problem,the basic thing is not relying on the increase of birth rate. The best solution is to establish an effective social security system.
