In recent years, many famous stars have been hired by universities. People hold different opinions about this.
    For those who are in favor of it, hiring famous stars can encourage students who are their fans. What’s more, it can also make the university better known. However, others are against it. In their opinion, not having received any training on how to be a good teacher, the stars can’t do the job well. Besides, they are too busy to really communicate with students.
