Legal analysis: the policy of double reduction has an impact, but adult education and certificate examination training education are not prohibited. Various localities and departments have carried out a series of rectification actions. The participation of the regulatory authorities will undoubtedly further promote the normalization and efficiency of supervision. In the future, the time, content and fees of off-campus training institutions will be subject to stricter supervision.
