Five stories to help you 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 operators 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 a single "cunning merchant" can manipulate.
Key reminder.
The greatest value of this story isn't teaching you how to harvest retail investors.
It's telling you: don't believe in "guaranteed profits," don't chase "endless rallies."
Greed is human nature's weakness, and operators bet on exactly that.

Story Two: Hardware Equipment Sales.
Hire 400 salespeople, base salary 100k, quota of 5 units.
End result: 30 people remain, 600 units sold, millions in profit.
This model sounds brutal, but has one prerequisite.
The product truly has demand, and truly has competitive pricing.
Otherwise, 400 people won't sell anything, and the boss loses first.
A reminder for people wanting to learn "leverage."
Don't just learn tactics, learn the product.
Sales is an amplifier, not an engine.
Bad product means the more tactics, the faster you die.

Story Three: Planned Obsolescence.
Lightbulb lifespan capped at 1000 hours, phone systems get slower with each update.
This is called the "yin-invading-yang trap," sounds mystical, but it's just business strategy.
But here's the thing.
Quality too good, company goes bankrupt.
Quality too poor, brand collapses.
That middle balance point is the real skill.
Advice for consumers.
Don't expect products that "last a lifetime."
Don't believe marketing like "pricier means more durable."
Read reviews, compare specs, calculate residual value.
Rational consumption matters most.

Story Four: Supermarket Prepayment Model.
Pay 1000 get 1000 bonus, then another 1000 back, lock in users for 2 years.
1500 people pay up, 150 million in cash flow collected.
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 cost to protect rights, low chance of recovery.
Second, consumption lockdown.
You think you got a deal, but you're actually trapped.
Don't want to go? Forced to go or your money's wasted.
A lifesaving tip for people considering prepayment.
First, don't chase huge discounts.
Pay 100 get 20 is fine, pay 1000 get 1000 requires caution.
The crazier the discount, the bigger the risk.
Second, choose established chain brands.
Small shops have low cost to disappear, big brands have high cost to breach.
Better to get slightly less discount, gain more security.

Story Five: Currency Circulation and GDP.
1000 yuan circulates 5 times, creates 5000 yuan GDP.
Two people trade feces for checks, creates 100 million GDP.
The story exaggerates, but the logic holds.
Cash must circulate to create value.
Speculation always exists in the economy.
But don't be led by "encourage consumption."
Capitalists want you to spend because without your spending, they don't earn.
But your money is your blood and sweat, not their harvest.
Spend what should be spent, save what should be saved.
Don't be hijacked by "circulation creates value."

Finally, the truth.
These five stories are fundamentally "human nature + rules" games.
Greed, fear, chasing bargains, fear of loss.
These emotions are the underlying fuel of economic operation.
But stories are simplified, reality is complex.
Don't finish the stories and think you understand the economy.
People who truly understand economics don't teach you to get rich through stories.
Core advice for ordinary people.
Don't think "understanding the economy" makes you wealthy.
First, do your current job well, practice your skills solid.
Economic cycles rise and fall, but ability is hard currency.
