The implementation of “Double Reduction” policy is a systematic social governance measure，and community education，while adhering to the concept of serving the whole people’s lifelong learning with corresponding functions and capability to serve the aim of “double reduction”，plays a pivotal role in the communication between schools，families and communities. Relying on the community education service system，Beijing has taken the initiative to carry out practical exploration of “double reduction” of services. Under the current situation of lacking social awareness，shortage of funds，insufficient venues and small reserve of talents，through innovating work paradigms and by working with social forces，the “home-school-community” collaborative education mechanism and family co-learning mechanism have been established and implemented with remarkable practical effects. For future prospects，the focus is on the grassroots level，only by continuously strengthening the overall management capability of the district-and county-level governments on community education，facilitating high-quality development of community education，guiding the reform of school education with the concept of lifelong education，vigorously developing family education，and designing high-quality home-school-community education programs，will a long-term “double reduction” mechanism for community education services be formed，and the fundamental task of morality building and talents cultivation be consolidated.
