What does the L-sign service of Hong Kong and Macao Pass mean? Do I need a Hong Kong and Macao Pass to go through customs?

The L sign of the Hong Kong and Macao Pass is "Team Tour". You can't go through the customs with personal documents, you must go through the customs and return with the team under the leadership of the team leader.

Only those who sign G can go in and out of the customs alone. Residents in 49 cities across the country can sign G, while residents in other places can only sign L.

Some travel agencies often temporarily assemble L-sign people into a team and send them out of the customs. This service is called "L-sign delivery service".
