The whole island of Hengqin has basically met the conditions for closed customs operations. After the customs closure, 7 "second-line" channels for external communication will be set up.

There are plans to build a new customs inspection facility in the Maozhou Tunnel to further facilitate travel out of the island. The construction period is reversed according to the 0:00 closure operation node on March 1, and responsibilities are compacted. The operation of branch line management and customs closure has no precedent to follow.
