Don't belong. Teaching physics to children is not beyond the scope of business. Because fitness service belongs to the service industry, its business scope includes providing fitness consultation, fitness guidance, fitness training and other services. Physical fitness class is a physical education course for children, which aims to help children improve their physical fitness and sports ability. Therefore, fitness service companies provide physical fitness courses within their normal business scope, not beyond their business scope. For children's physical fitness courses, we need to pay special attention to safety issues to ensure that children are fully protected and cared for in the course.
