First, if you graduated from Film and Television College, there will be many opportunities for recruitment and recommendation, so it is easier to enter the crew.
Second, if not, it is also good to know stars and have a good relationship, such as a makeup artist who helps stars make up.
Third, no, then you need to wait for an opportunity. In fact, many places shoot their own dialect dramas, so the requirements are low. You can be a volunteer.
Suggestion: You can go to the photo studio and wedding photography first and make up well. It is always a talent, and talents have the opportunity to enter.
