What's the noise of thieves breaking into houses?

The sound of a fine hammer, tick-tock.

It's usually not that loud, but it has a frequency. Listen carefully, there are light footsteps.

Don't panic when you meet a thief breaking into a house. Once you panic, your mind will be abnormal. Don't pull out the key after locking it. Secondly, be sure to know the telephone number of the property, and inform the property as soon as possible. Anyway, their security guards can get there in the first place. Call the police or try to tell the neighbors for help.
