Legal analysis: illegal, private cram schools are illegal, and it is illegal to gather people during the epidemic. The Education Bureau clearly stipulates that in-service teachers can't make up lessons for students privately during the holidays, which means that they can't run cram schools during the summer vacation.

Legal basis: Article 50, Paragraph 1, Item 1 of People's Republic of China (PRC) Public Security Administration Punishment Law refuses to carry out the decisions and orders issued by the people's government in an emergency, and it will be given a warning or a fine of less than 200 yuan; If the circumstances are serious, they shall be detained for not less than five days but not more than ten days, and may also be fined not more than 500 yuan.
