I am currently working in a hotel. How can I kill time?

I'll tell you a way: 1. You can count the traffic and people passing by every hour and what kind of cars they are.

2. You can recite a few poems before going to work, four poems a day, which is 120 in January.

3, you can practice holding your breath several times to see how long you can hold it, which is useful for diving, but you will make a fool of yourself if you don't hold your breath.

Find another way for yourself.
