Went through Lok Ma Chau on Sunday and had the new form which is a one piece one with 2 sections to fill out, and they tear off one section and hand it back for you to use on the exit journey. Is this the one they are also using at Lo Wu?
Sounds like it. The Lo Wu one is yellow.
I had no problem finding a bunch last week. Hope they aren't planning to hand them out one at a time forever. Eventually my stash will need to be replenished.
My experience is that the new forms were first brought in at the "new Huanggang" checkpoint ie Lok Ma Chau/KCR checkpoint (Lok Ma Cha spur line) and are now at LoWu. The "old Huanggang" checkpoint (ie bus/road checkpoint) accepts the exit section from the new two-part forms but is still basically using the old forms. The "old Huanggang" checkpoint may be moving to using the new forms - just not clear yet.
At both LMC and LoWu they seem to be handing out the new forms as if they were ration tickets. Hard to get a good supply of them but I hope this changes.
The immigration people at the "new Huanggang" seem to be freshly trained and keen to try their English as this is the first place any of them have ever spoken to me. The customs at the "new Huanggang" do not have much to do and will inspect luggage far more often and far more officiously than at LoWu and once they have decided to inspect your baggage they are overbearing and determined to find something. Tomatoes and avacadoes are on the "banned list" but I had onions from a supermarket impounded.
