If there is no electricity in a community, I think you can call and ask the management of the property. The property management should know this. This may be a temporary power outage. If the circuit is broken, he should know it. be repaired.
This situation occurs often in our house. There is often a power outage in a certain area and the circuit needs to be repaired. And even if there is a problem in your community and there is a sudden power outage, you have no choice but to wait for the electrical repairman to arrive. At that time, as long as you give feedback to the property management company, I believe they will definitely find someone to take care of it. Even if you don't say it, other residents will.
At this time, you can use the spare desk lamp at home, or light a few candles to make your walk easier. If your phoneéphone is still powered, you can play with it. If your phone is running out of battery, you can also read a book at home with a desk lamp. If you feel that you are doing well at home, you can also go out for a walk. I think it's impossible for the whole world to have a power outage. Basically, find something to do on your own and wait for the call to come.
