"Sister, sister, …" A voice called and Qin Wu turned to see a young boy.
The boy was about six and looked a little malnourished.
However, he had bright eyes and the way he looked at Qin Wu was like looking at a saviour.
Qin Wu sighed and plastered a smile on her lips.
"Little boy, can I help you?" She asked.
"I can tell that sister likes to be clean." The little boy said in a confident voice.
"How do you know?" Qin Wu couldn't help but cooperate with the little boy.
"My sister is wearing white but she isn't dirty. Does my sister want to buy detergent and bathing soap? I know the best place to buy these things?" The little boy said, proudly thumping his chest.
A moment later, he looked around and signalled Qin Wu to come closer.
"Sister, you don't want to buy these things in the official shop." The boy whispered and Qin Wu narrowed her eyes.
'Is there an underground market already?' She wondered.
