The Big Problem: Why Was Shopping So Hard?

Imagine you’re holding a shiny, brand-new toy spaceship. It’s got flashing lights, real sound effects, and wings that actually move! You’ve seen it in a magazine, and you’ve dreamed about it for weeks. But when you ask your parents to buy it, their smiles turn a little sad. “It’s a bit too expensive, sweetie,” they say. “Maybe for your birthday?” Your birthday is *six months away*. Sound familiar?

Now, let’s take a trip to a different house, in a big, bustling city. A kid there points at the same toy spaceship in an online catalog. With a few clicks, their parent finds a sale, uses a coupon, and—boom!—the spaceship is on its way, delivered in two days. The price? Less than half of what your local store charges.

What just happened? Why did one child’s dream toy feel like a treasure locked in a vault, while for another, it was just a click away? This, my friend, is the big problem we’re going to unravel. It’s a story about hidden doors, secret rules, and a world where finding a good deal felt like being part of a special club that not everyone got invited to. For a long time, shopping for cool stuff—especially for families in smaller towns and rural areas—was like trying to solve a super tricky puzzle with missing pieces.

The Invisible Walls: When Your Zip Code Changed Your Price

Let’s pretend the whole country is one giant playground. In the best, sunniest part of the playground (the big cities), the slide is new, the swings are shiny, and the candy store has every flavor you can imagine, all at fair prices. Kids here know all the shortcuts to get the best treats.

Now, walk to the far, far edge of the playground. The grass is a little patchier, the slide is older, and the candy store? Well, it has *some* candy, but the good stuff is either missing or costs *twice* as much. Why? Because getting that candy from the city store to this far-out spot is like sending a tiny explorer on a long, hard journey. The explorer (the toy) has to pay “tolls” at every bridge (the truck driver, the warehouse, the local shopkeeper). Each toll adds a little more to the final price. By the time the toy spaceship reaches the shelf in the small-town store, it’s collected so many tolls that it’s become a luxury item!

This is called the “last mile” problem. Think of it like this: a farmer grows delicious, juicy apples. To get those apples to you, they travel on a long relay race. The farmer sells them to a big collector. The collector sells them to a distributor. The distributor sells them to a regional warehouse. The warehouse sells them to a local supermarket. At every single handoff, someone adds a little fee for their work—their “toll.” By the time the apple rolls into your shopping cart, its price has been bumped up at every single step. For people living far from the big distribution centers, these “toll bumps” were higher and more frequent, making everything cost more.

Real-World Example: The Toy Kingdom Gap In China, where our story takes place, this was very clear. In 2015, a mom in Shanghai could buy a popular building block set online for about 150 yuan (let’s think of it like 150 “fun-dollars”). But a mom in a small village in Sichuan province might see the *exact same toy* in her local shop for 280 yuan! That’s almost *double*! The toy came from the same factory, but because the journey to the village was longer and had fewer customers to share the costs with, each toy had to carry a heavier price burden. It was like the toy had to pay for its own lonely road trip.

The Secret Club: When “Good Deals” Required a Secret Handshake

Okay, so prices were higher in some places. But what about those amazing online deals? Couldn’t everyone just shop online? Well, here’s the second wall: the “secret club” wall.

Early online shopping was a bit like a fancy, members-only warehouse. To get the *best* prices, you needed to do things like:

• **Buy in bulk:** “Get 10 of the same item for a lower price per piece!” But what if you only wanted *one* toy spaceship? You were out of luck.
• **Have a membership:** Some sites had annual fees. Pay the fee, and you get “special prices.” No fee? Pay full price.
• **Be a “power user”:** You had to log in every day, play little games, collect points, and become a “VIP” to unlock discounts. For a busy parent or a kid without a smartphone, this was a full-time job!

This system loved people who lived in big cities, had fast internet, and could spend hours hunting for coupons. It was less friendly to families in smaller towns who might have slower internet, less familiarity with complex apps, and certainly less time to play online games for a 5% discount. They were standing outside the clubhouse, peering in through the window, watching the cool kids get all the good deals.

A Day in the Life: Mei vs. Leo

• **Mei** lives in a small town. Her family runs a little fruit stand. To buy a birthday gift for her friend, she and her mom walk to the only department store. The toy they want is the only one on the shelf. Price? Take it or leave it. They have to save for a month. Mei learns to want less.
• **Leo** lives in a metropolis. His dad opens an app on his tablet. He sees the same toy. But wait! There’s a **flash sale** for the next hour! And if he invites three friends to also buy one, they all get an extra 20% off. Leo texts his friends. Five minutes later, the deal is locked in. The toy arrives in two days, cheaper than Mei’s local store price. Leo learns that shopping is a game, and he can win by being quick and social.

Two different realities. Two different lessons about value and access. The system wasn’t *trying* to be unfair; it was just built in a way that accidentally left a lot of people on the outside looking in. The “good deals” were hidden in plain sight, but you needed the right map (a smartphone, digital literacy, a big social network) to find them.

The Lightbulb Moment: A Young Man’s Big “What If?”

Now, meet our hero. His name is Colin Huang (黄峥). But when he was a kid, everyone just called him by his Chinese name, Huang Zheng. He wasn’t a billionaire in a suit; he was a kid who also wanted cool toys. He grew up in a regular family in the city of Hangzhou. But here’s the important part: he spent a lot of time visiting his grandparents in the countryside.

From the backseat of his parents’ car, young Colin saw the two worlds slide past his window. He saw the gleaming towers of the city and then the quiet, winding roads of the villages. He saw the big, busy supermarkets and then the small, crowded corner shops. And he heard the stories.

He heard his rural relatives talk about how much things cost. How a simple appliance, a piece of clothing, or a toy for a nephew felt like a big investment. He saw the effort it took for his aunt to save up for something. At the same time, he saw the mountains of stuff in city malls and the endless scroll of items online. A question began to buzz in his young mind, like a persistent mosquito:

“Why is it so hard for the people I care about to get the things they want? And why is it so easy for others?”

This question didn’t go away. It grew with him. Colin was a super-smart student. He won a prize that let him study computer science at one of China’s top universities, Zhejiang University. Then, he got a scholarship to go even farther—to the United States, to study at the University of Wisconsin. He was learning about computers, about the internet, about how information could travel at the speed of light. But he never forgot that mosquito question.

He worked for a big tech company in the U.S., Google. He saw how the internet could connect people instantly. He saw how information could be free and flow everywhere. But he also saw that this digital river mostly flowed *between* big cities. The little streams that went to the villages were often dry.

After a few years, he went back to China. He tried a few business ideas. He started an o
