What is the telephone number for consulting underage interns for how many hours?

Hello, I would like to ask what phone number I can call to consult underage interns for a few hours. How many hours can the Education Bureau ask underage interns to practice? The Ministry of Education announced the management hotline of students' internship in vocational colleges. This hotline is dedicated to receiving policy advice, suggestions and related issues on the management of students' internships in vocational colleges. Therefore, the Education Bureau can call underage interns and ask them how many hours they want to practice.
