"Knock, knock, knock."
"Come in, please."
Hearing the knock on the door, Song Yao stopped what she was doing and looked at the door.
Anna walked in with a document in her arms, "Ms. Song, this is the information you asked for before." "Well, put it on the table. Thank you."
"Okay."
Putting down the file, Anna continued, "Ms. Song, besides, you have asked me to track down the fire in the clothing factory and come to a conclusion. The fire was an accident. The employees in the factory didn't extinguish their cigarette butts completely after smoking. In addition, the factory is dry, which caused the fire." Hearing this, Song Yao frowned and repeated in a low voice, "An accident?" She had imagined all kinds of possibilities, but she didn't think that the fire in the clothing factory was just an accident.
