What are the procedures for the crew to shoot outside the mirror? How does the equipment go through customs?

It is estimated that what you are asking is mainly about photographic equipment and other equipment entering and leaving the customs. It is suggested to find an entity such as a film and television company in China and apply for ATA documents from the local China Council for the Promotion of International Trade in their name.

We only need to pay a certain amount of deposit to the China Council for the Promotion of International Trade and return the deposit after returning to China within six months.
