How to arrange the room number on the first floor of the restaurant?

The room number on the first floor of the restaurant is arranged as follows:

1, realizing single and double-sided arrangement. When designing the hotel room number plate, the hotel signs are single room and double room, and the odd and even numbers are staggered.

2. Go to the principle of "4" and "7". When sorting hotel room numbers, go to "4" and "7" because 4 and 7 are unlucky.
