It took considerable effort to calm Xiao Mei's emotions before Qin Hai and Qiao Wei helped her sit down in a chair.
Qin Hai asked, "Sister Mei, when did your daughter go missing, and does she have any distinctive features, like birthmarks?"
Wiping her tears, Sister Mei sobbed, "She went missing ten years ago, just as Tongtong turned five. Early in the morning, she went to the market with me to buy groceries. I turned around for a moment, and Tongtong had vanished. Someone told me that a middle-aged woman had taken her by the hand and walked away, but no matter how long I searched, I couldn't find her. Even the police couldn't help... Over the years, I always went to Nanwan Market to look for Tongtong, but I never found her."
Qin Hai sighed silently; no wonder the middle-aged woman from the cleaning company said that Xiao Mei often loitered near Nanwan Market. It seemed certain her daughter had gone missing there.
