There is a sign hanging on the shutter door to leave temporarily.

When you leave temporarily, you can write the following two signs on the shutter door:

1. If you need to go out for business temporarily, you can write "Go out for business, please don't disturb" and then leave your name and phone number.

2. If you leave temporarily due to business trip, you can write "Leave temporarily, expect to come back (specific time), if you need it urgently, please call (specific phone number)" and leave your name and phone number.

These are the signs that can be written on the shutter door when you leave temporarily. I hope I can help you.
