Dong Chang's neighborhood was less than ten minutes away from Zhang Nan's house. They had probably chosen a place close to the company to make it easier for them to go to work.
Meng Heng led them to Dong Chang's house and knocked on the door.
Soon, a female voice came from inside the house. Mother Dong stood warily inside the door and shouted, "Who is it?"
Meng Heng answered in a clear voice, "Auntie, it's me, Little Meng. We would like to ask you more questions. Can you open the door for us?"
Mother Dong looked through the peephole and saw the young police officer standing outside the door. She rubbed her hands nervously, then hesitantly opened the door and said, "It's you. Why are you here again? Haven't I already told you everything that you need to know?"
Meng Heng smiled politely. "Auntie, I'm sorry to disturb you. I'm here because I need to verify some details with you. Can we talk inside?"
