There are more than 200 million students in China. As Minister of Education Chen Baosheng said, "stopping classes without stopping studying" can be described as "unprecedented and unprecedented", which is a great pioneering work and a miracle of the development of education. This "suspension of classes" means that we have mobilized a lot of manpower, material resources, financial resources and intelligence in a very short time to meet the needs of all young students who are affected by the epidemic and cannot start school on time. It should be said that in just two or three months, we have completed a process that originally took 10 years to complete.

Over the years, our education informatization has laid a good foundation. This time, the public classrooms of educational TV stations have been opened for some places that cannot be covered by mobile phone networks, so as to cover all students and realize the fairness of educational resources.

Through the investigation of this epidemic, we can see that there are still some new situations and problems in large-scale online education. It has accumulated a lot of valuable experience and opened up new ideas for future education and teaching reform.
