I'm from China Southern Airlines, not Jincheng College, but I think it's similar. Freshmen are required to get to school early every day, and I don't care after sophomore year. As long as you don't attend class, no one will take care of you if you don't get up one day, and the lights will be turned off at eleven o'clock in the evening. How many classes you take in a week depends on how many elective courses you choose besides the compulsory courses. You can leave school at any time. Unlike high school, universities are more free.
