The homework and off-campus training of primary and secondary school students in my country have become a heavy burden for students’ physical and mental growth and educational ecological operation. In response to this，the state has proposed and implemented the “double reduction” policy of great significance. As the forerunner of education reform，Beijing’s practical experience in the implementation of the “double reduction” work has guiding and reference value. At present，Beijing has launched a number of measures to reduce the workload of students，improve the quality of after-school services，regulate off-campus training，optimize the quality of school education，and improve the coordination mechanism. However，there is still a need to continue efforts in forming a correct educational concept，promoting the all-round development of students，improving the level of school education，and creating a collaborative education environment.
