Is it a waste for college students to work in the crew?

Every profession has its own code of ethics. Can't say it's a waste. The graduates of the Film Academy all entered the film crew through the relationship between schools, teachers, classmates and friends. When they graduate, there will be a graduation performance, in which crews, companies and performing arts units from all over the country choose candidates. Those who are not selected can also go to the tour group after graduation, and only accept graduates from professional colleges.
