Do you charge for part-time models?

I can tell you that any company that is formally engaged in cultural media, communication, brokerage and planning does not charge employees (including part-time jobs) and mortgages.

After signing contracts with employees (including part-time models), the company pays for training, publicity, packaging and other expenses. Some companies in Beijing spend tens of thousands to hundreds of thousands of dollars a year on models and artists.

And those companies that charge for registration, training, counseling, planning and image packaging of models or actors are not cheating. What is it?
