Excuse me, what is the customs clearance time for the first time to leave Luohu Port after settling in Hong Kong? Thank you!

I haven't studied it, but don't be too early, because Luohu doesn't open until 6 am and closes on 12 in the afternoon.

As you enter the country with a one-way permit, you'd better go during office hours, that is, between 8 am and 5 pm. Because the entrance with one-way permit is a special passage, just like when you enter the Luohu Bridge on the Hong Kong side, there is an entrance on the left side of the bridge for new immigrants with one-way permit. So for the sake of safety, it is best to enter during office hours.
