Dai Li, who was sleeping, was suddenly awakened by a sudden knock on the door, which scared her to sit up from the bed. She thought it was a dream of someone knocking on her door in her sleep. She listened carefully and found that the knocking was still going on. , The sound of bang bang, one after another, in this midnight, makes people feel frightened.

The weather is so cold, who will come to her in the middle of the night?

Dai Li grabbed a coat and put it on. She came to the living room and looked out through the peephole of the door. It didn't matter if she didn't look at it. She was so shocked that she dropped the coat she was wearing.
