One-on-one tutoring with students is not illegal, and any form of tutoring or remedial classes is illegal. It may just violate the relevant regulations of the Education Bureau and do not touch the bottom line of the law. However, if this kind of tutoring class fails, it may be sealed up or punished by the education department. If you have certain qualifications for running a school, you can set up cram schools in training institutions, give one-on-one tutoring, and then let students come to class. This is no problem, it is in line with the regulations. If you are not a regular educational institution and have no school license, but you let students come to your home for one-on-one tutoring, then you have violated the relevant regulations of the Education Bureau. Because you don't have a school license, even if you are a teacher, you can't run a school outside the school without permission. Your behavior violates the relevant regulations of the State Education Bureau. Therefore, this one-on-one behavior does not violate the relevant laws, but as a teacher, although this behavior is not illegal, it is illegal. In fact, in our country, there is no very clear stipulation that individuals cannot do paid tutoring activities. After all, many college students may be tutors when they work part-time, so tutoring activities are not prohibited, but the state does not advocate it. After all, many times parents and children have such needs, but teachers are forbidden to pay for tutoring, so if you are a teacher, it is illegal for students to come to your home for one-on-one tutoring. The state stipulates that teachers teach and educate people. They should not aim at making money and making profits. The main development direction should be how to educate children and let them accept more knowledge. So if you are an in-service teacher, you ask students to come to your home for one-on-one tutoring. If you don't collect money, then you haven't broken the law. If you take money, then you didn't break the law, but you did. But if you are a one-on-one tutor for college students, it is understandable to invite students to your home for tutoring. You have not violated the relevant regulations, let alone the law. So it depends. In short, one-on-one tutoring may involve violations, but it will not involve violations.
