What does the L port logout service mean?

Generally, the Hong Kong and Macao Pass issued by the mainland is L-shaped, which means tourist visa. Generally, you need to travel with a group to get through. Some people want to go through customs by themselves. At the customs, some people provide delivery service. Generally, they need to charge 30 yuan, which means that you are a tour group and you can pass the customs.

The other visa is the G visa, which means that the individual visa does not need to charge this fee. Generally, this is because the hukou visas in different regions are different, which is not something you can choose.

This is the previous requirement. From 20 17, even if I signed it, I forgot whether I didn't need customs clearance service. I went to Hong Kong for Christmas in 20 17, and I didn't pay for the customs clearance service.
