The reason for online teaching is that the situation of epidemic prevention and control in China is severe and complicated. COVID-19 epidemic has occurred in many provinces and cities, and there are many local cluster epidemics in families, schools and communities, so the pressure of "preventing imports from outside and rebounding from inside" is greater. In order to ensure the health and safety of teachers and students in the city, it was decided through research that some primary and secondary schools in our city changed from offline teaching to online teaching, and all kindergartens and various off-campus education and training institutions stopped offline teaching. It is hoped that teachers and students in the city will consciously assume the responsibility and obligation of prevention and control, and lay a solid foundation for ensuring the overall stability of epidemic prevention and control.
