Where can Chengdu recruit part-time extras?

It seems that there are fewer crews in Chengdu, and many of them are dishonest and easy to be cheated. You can go to some websites of entertainers with high integrity, and their cast information is more comprehensive. Of course, it is best not to go to those websites that charge fees. Now there is a website on the Internet called China Radio and Television Talent Network, and the crews on it all have shooting license numbers issued by the State Administration of Radio, Film and Television. May I wish you early success!
