How to send a circle of friends when there is no electricity to climb the stairs?

You can send such a circle of friends when you have no electricity on the stairs:

1. Today's happiness is that the power outage lasted for one day. The moment I finally stepped into the corridor after a hard day, I suddenly let out a cry. I was so happy when the world went from darkness to light. When climbing the stairs, don't look down, or you will find that you still have a long way to go. There was a power failure, so I had to climb the stairs without the elevator, which made me experience the truest feeling of climbing the mountain.
