When students in vocational colleges in Henan province use the "vocational school master" practice punching system, there is indeed a requirement for punching days. The Henan Provincial Department of Education requires students to complete at least 180-day clock-in records in the "home of vocational schools" during their internship to meet the graduation requirements.
If students don't reach enough clock-in days, it will affect their normal graduation or fail to obtain graduation certificates as scheduled. Therefore, in order to successfully complete their studies and obtain graduation qualifications, students should ensure the completion of the required practice punching days according to the requirements of schools and education departments.
