Brother Dali Trading Stocks

What's Gu Feifei saying? Increases and graphs? Why does it sound like she's talking about the stock market?

Out of curiosity, Hong Dali leaned forward. He saw several small sectors on the projection, each filled with multiple graphs. On the top left corner, figures about highs, lows, and the daily range were displayed.

Isn't this the stock market?

"You rely on this to make money?" Hong Dali stared with wide eyes. "Stocks! I always feel like those who trade stocks are experts!"

"I buy in small amounts just to earn some money for elixirs." Gu Feifei stared intensely at the holographic projection. "What else can I do to make money? I need to train and attend lessons usually. Nobody will dare to employ me for part-time jobs. Trading stocks is my only option."
