Social Security is a social safety net and Stabilizer, and is directly related to the vital interests of the hundreds of millions of people. Since the Third Plenary Session of the Sixteenth CPC Central Committee, China's social security system has achieved remarkable results, and played an important role to protect and improve people's livelihood, to maintain social harmony and stability. Meanwhile, with the continuous development of our economy and society, the new situations and new problems of population aging, urbanization, employment diversification are emerging, which constitute the new challenges of China's social security system to establish and improve in the new era. Therefore, accelerating the integration of the social security system, further improving the social security system, forming a scientific and effective management of the social security system, will be the main direction of our social security work in the future. <<
