临时 (lín shí): temporarily; temporary

I originally planned to go to the movies this weekend, but something came up at the last minute, so I had to refund the ticket.

The meeting was temporarily changed to 3 PM; please everyone pay attention to the time change.

Due to the weather, the flight was temporarily canceled, and we had to stay overnight near the airport.

He was called away on a business trip at the last minute, so he couldn't attend his daughter's birthday party.

This restaurant is too busy, so we decided on the spot to switch to another one to avoid eating too late.
