The general trend of population and development is characterised by rapid population ageing, which is one of the irreversible changes and the basic national conditions in current and future China, determining the long-term nature of the challenge and the arduousness of the task. Since the beginning of this century, especially since the 19th National Congress of CPC, CPC's great concept on actively dealing with population ageing has improved in practice and consolidated the population support system for building a moderately prosperous society in all respects. On the centenary of the founding of CPC, the establishment of a comprehensive and integrated system awareness, and the implementation of the national strategy to actively deal with population ageing are important foundations for adapting to the deep ageing society during the 14th FiveYear Plan period, and necessary preconditions for opening the new journey to build a socialist modern country in a holistic way. Specifically, it is necessary to consolidate economic wealth reserves, enhance political governance capabilities, cultivate cultural values, ensure peoples livelihoods, and promote ecological civilization construction according to the Fivesphere Integrated Plan.
