Qiao Lian got out of the cab and walked into her neighbourhood.
This time, she felt again as though someone was following her.
She frowned and spun around. Nothing was out of order.
Still frowning, she walked towards the market, bought some vegetables and went up to her apartment.
After Qiao Lian got into the lift, Shen Liangchuan stepped out of the van.
He was wearing his sunglasses and a baseball cap. Staring at the lift's panel, he saw that it had stopped on the sixth floor.
He furrowed his brow and went into the lift.
When he stepped out of the elevator on the sixth floor, he discovered that there were two apartments there.
He frowned again. Looking for Qiao Lian like this was like a game of probability.
He walked to one of the apartments and knocked on the door.
Then he pressed the doorbell twice. He heard Qiao Lian's voice yell, "Who is it?!"
