Let's open a new KTV! There are 44 private rooms in total ~ how to code the room number?

First of all, it is divided into three areas for easy management!

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.
