The truth behind that incident

"Why did you two leave the house!?" On the other side, Madam Kong was hugging her two daughters and crying with relief. "Why did you two run out? Do you know how worried I was?" 

She did not sleep a wink last night or this afternoon, she had been looking around the city with Yu Dong.

Fortunately, Yu Dong found the tuft of fur that was lying on the street and recognised it. The two women then set off at once and because they didn't want to miss the trail, they dared not to use a carriage. 

While looking for the children on foot, Madam Kong was worried about their safety all the time. 

Sometimes the sight of her daughters crying, or getting bullied flashed in front of her eyes, which made Madam Kong lose her mind.

She knew that since they could not find her daughters in the city, it meant that they were taken away by human traffickers instead of refugees.
