If the landlord is in Beijing, you can go directly to the gate of Beiying, where there are cars specially designed for group performances. If you don't know much about it in other cities, I'll teach you a few simple ways to distinguish it.
First, you can directly check the name and telephone number of their company to see if there are any bad records online. Some companies cheat many people, and some send messages online.
Second, if you don't have this information online, you can make a phone call and ask them about it. Ask them if they are intermediaries, and whether they need to pay meals, accommodation and training fees in advance. Most people who have to pay in advance are liars.
It doesn't matter. You can go on a field trip and make a conclusion.
Also, is the treatment good? Impossible, extras can only get about 30 yuan and a box lunch every day. Competition with groups and special actors is fierce. Unprofessional, well paid, basically unreliable.
I hope what I said is helpful to the landlord. You can leave a message and ask me if you don't understand.
Supplementary landlord's question: "Tengfei Film and Television" said that there is a labor contract, is it credible?
A: Saying that there is a labor contract and signing a labor contract are two different things. It is not credible to ask you to pay any training fees, accommodation fees and catering fees before signing the contract, and then exploit loopholes in the contract to escape the liability for breach of contract and let you suffer dumb losses. If there is no charge before, you can study the contract carefully. You can tell the company that you want to take the contract home. If the company doesn't agree, it is obviously a ghost. If you agree, study the words on the contract carefully when you get home.
