Is it true that the dubbing of novels in the same city is a part-time job?

Part-time dubbing does exist, and it is real, reliable and profitable. However, ordinary people really can't do this kind of work. Don't listen to those dubbing training propaganda. After the training, it seems that many part-time jobs are waiting for us to choose and money is waiting for us to get. This is an industry in short supply. It is not easy for ordinary people to make money by dubbing novels and articles.
