Bobai, a temporary worker, has something to do with music. Where is this work?

Ah, there are many, such as CJOL, 5 1JOB and so on. In general, temporary jobs in music are really hard to find. I suggest you ask in some communities in large and medium-sized cities. For example, in various festivals, sometimes some parties are held in the community. Maybe you can improvise, and then you can use your talents!
