Legal analysis: it is illegal to open a cram school without permission. 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. All in-service teachers use the winter and summer vacations to run classes without the approval of the Education Bureau, because teachers have the right to rest and participate in training, and these rights of teachers should be safeguarded during holidays. Therefore, it is basically illegal for in-service teachers to use holidays to run classes, which should be strictly prohibited. What has been done should be banned.

Legal basis: decision of NPC Standing Committee on amending the Education Law of the People's Republic of China. Article 25 is renumbered as Article 26, and one paragraph is added as the third paragraph: "Schools and other educational institutions run by the state shall adhere to the principle of thrift." Paragraph 3 is renumbered as paragraph 4 and amended as: "Schools and other educational institutions established or participated in by financial funds or donated assets shall not be established as profit-making organizations."
