What procedures do you need to go through to be an extra actor in Hengdian? Where is the specific address?

You don't need to go through any formalities to go to Hengdian Studios. If you go through an intermediary, maybe you can.

Zhejiang Hengdian Film and Television City needs a large number of extras here every day, but unlike Beijing, we have to find them ourselves. Because there are many crews shooting on the set, you can go over and tell the field staff that they will bring people if necessary.

The specific address is located in Hengdian Town, Dongyang City, Zhejiang Province, China. When you get there, you will enter the ancient times. I went there to play two months ago! !
