Zone a, zone b and zone c
Area A starts from A50 1 and goes back.
4 don't use it.
Zone B starts from B60 1 and goes to the back row.
Do not use the same 4.
Area C starts from C80 1.
And no 4.
It's easy to manage.
It also gives people the feeling that there are many boxes.
Give people a feeling of atmosphere.
