In order to study the willingness of teaching and learning participants to carry out online teaching by the initiative "ensuring learning undisrupted when classes are disrupted", two specific groups of students and teachers were taken as research objects. Online questionnaire survey was conducted through the questionnaire star platform, and 628 valid questionnaires were statistically analyzed by SPSS software.It is found that students are more willing than teachers to adopt online teaching and approve of its effect; old teachers more than the new teachers agree with this kind of teaching form; primary school teachers more than university teachers think highly of this kind of teaching method. Teachers and students think that the best way to solve the problem of delayed teaching due to the epidemic is online teaching by the initiative "ensuring learning undisrupted when classes are disrupted", followed by the use of summer holidays and weekends to make up lessons. However, there are still many difficulties and problems in the implementation of online teaching, especially for students and teachers in rural areas.
