In short, the aunties were the living map of this city. They were always able to find places where the prices were cheap and the items were especially good. They ended up becoming a cheap and useful source of recommendations.
In the end, it turned into a cheap and useful recommendation.
For example, they would tell somebody that a certain locally produced face mask was better than another face mask brand with the same materials. They'd tell someone that after using a cheap yet useful vitamin ointment developed by the beauty department of a certain hospital, it would lighten sunspots and shrink the pores.
The aunties shared their wisdom with others. The town was very lively.
When Ye Tianxin saw the news online, she could not help but laugh.
Even Fang Nan took out her notebook to record their advice. Then, she searched for the vitamin ointment that the aunties mentioned and realized something. "Tianxin, that vitamin ointment is already out of stock."
