Five stories to understand the economy.

Story one: The mango scam.
Merchants create demand, drive up prices, induce herd behavior, and harvest retail investors.
Translation: This is a simplified version of stock market manipulators and real estate cycles.
But reality is more complicated.
Stocks have regulation, information disclosure, and short-selling mechanisms.
Real estate has policy, credit, and demographic structure.
It's not something one "cunning merchant" can control alone.
Key reminder.
The greatest value of this story is not teaching you how to fleece people.
It's telling you: don't believe "guaranteed profits," don't chase "endless surges."
Greed is human nature's weakness, and manipulators bet on exactly that.

Story two: Hardware equipment sales.
Hire 400 salespeople, base salary 100k, sales target of 5 units each.
End result: 30 people left, 600 units sold, ten million profit.
This model sounds brutal, but has one prerequisite.
The product truly has demand, truly has competitive pricing.
Otherwise 400 people can't sell anything, and the boss loses first.
One reminder for people wanting to learn "leverage."
Don't just learn tactics, learn the product.
Sales is an amplifier, not an engine.
Bad products mean more tricks equals faster death.

Story three: Planned obsolescence.
Lightbulbs last no more than 1,000 hours, phone systems get slower with each update.
This is called the "yin-invades-yang scheme," sounds mystical, but it's just business strategy.
That said.
Quality too good, company goes bankrupt.
Quality too poor, brand collapses.
That balance point in between is the real skill.
One tip for consumers.
Don't expect products that "last a lifetime."
Don't believe the marketing "pricier means more durable."
Read reviews, compare specs, calculate residual value.
Rational consumption matters most.

Story four: Supermarket prepayment model.
Charge 1,000 get 1,000, then return 1,000, lock in users for 2 years.
1,500 people pay up, recover 1.5 million in cash flow.
This model is common now.
Hair salons, gyms, restaurants all use it.
But risks are huge.
First, merchant disappears.
You paid, shop's gone.
High legal costs, low recovery odds.
Second, consumption lock-in.
You think you got a deal, actually you're trapped.
Don't want to go but must, money goes to waste if you don't.
One life-saving tip for people thinking about prepaying.
First, don't chase massive discounts.
Charge 100 get 20 is fine, charge 1,000 get 1,000 raises red flags.
The more outrageous the deal, the bigger the risk.
Second, pick big chain brands.
Small shops have low exit costs, big brands have high breach costs.
Better to save less and gain more security.

Story five: Currency circulation and GDP.
1,000 yuan circulates 5 times, creates 5,000 yuan GDP.
Two people trade feces for checks, creates 100 million GDP.
Story's exaggerated, but logic's right.
Cash only creates value through circulation.
"Hype" always exists in economies.
But don't let "consumption encouragement" sway you.
Capitalists want you spending because they can't earn if you don't.
But your money is your blood and sweat, not their harvest.
Spend what you should, save what you should.
Don't be hijacked by "circulation creates value."

Final truth.
These five stories fundamentally are "human nature + rules" games.
Greed, fear, getting deals, avoiding loss.
These emotions are the base fuel of economic circulation.
But stories are simplified, reality is complex.
Don't finish these stories thinking you understand economics.
Truly economically literate people won't teach you to get rich through stories.
One core tip for ordinary people.
Don't think "understanding economics" leads to wealth.
First do your job well, solidify your skills.
Economic cycles have ups and downs, but ability is hard currency.
