‘Cheap’ Is a Lie: The Cold Algorithm Behind 30,000 Stores

You work 14-hour days, manage a mountain of inventory, and finally hit 12,000 yuan in daily sales. You celebrate, thinking you’ve made it. Then you look up and realize your brand’s headquarters just opened another identical store 500 meters down the road. Welcome to the Zhao Yiming snack empire.

Most people look at the explosive growth of budget snack chains and attribute it to one thing: being cheap. But low prices are just the bait. The real weapon is a ruthless, data-driven “interception algorithm” that doesn’t just sell goods—it physically intercepts human traffic.

They don’t buy traffic; they intercept it. Anyone can wage a price war, but no one can replicate the cold math of predicting your exact route home.

Traditional retail, like shopping mall boutiques, relies on a traffic rental model. You pay exorbitant rent for a spot in a mall because the mall already has foot traffic. Zhao Yiming completely abandoned this model. Their site selection teams don’t look at how many people pass a corner; they look at how many 25- to 35-year-old women pass that corner between 5 PM and 7 PM. They map out the daily commutes, school runs, and evening walks of their target demographic and place physical stores directly on those mandatory paths.

Their formula is mathematically precise: a storefront width of at least 12 meters, corner lots prioritized for dual-direction exposure, and a minimum of 3,000 households within a 500-meter radius. They don’t want to be in premium shopping districts where people “make a special trip.” They want to be on the street corner you are forced to walk past on your way home. They don’t want your planned shopping; they want your impulse consumption.

Once the physical interception is set, the efficiency machine kicks in. Traditional supermarkets have inventory turnover cycles of 40 to 80 days. Zhao Yiming’s is 11.6 days. They aren’t a snack store; they are a rapid-turnover supply chain company disguised as a retail front. Combined with a staggering 6.2 monthly repurchase rate from local residents, the store transforms from a “traffic business” into a “stock business.”

Cheap is never a moat. It is merely the bait for the efficiency machine.

But this is where the fairy tale ends and the cold reality of franchise economics begins. The headquarters’ growth engine is fundamentally misaligned with the franchisees’ survival. The brand makes its money by supplying goods to franchisees. Every new store opened means more supply volume, more revenue, and a higher valuation for headquarters. For the franchisee, every new store opened means diluted foot traffic and a direct hit to their bottom line.

The math is unforgiving. A franchisee needs to hit 12,000 yuan in daily sales just to break even. After rent, labor, utilities, management fees, and the razor-thin 19% gross margin, the net profit is effectively zero. You need to push to 15,000 yuan a day just to make a meager monthly profit. But as the brand races to saturate the market—hitting a milestone of 30,000 signed stores—hitting that number is becoming mathematically impossible.

Headquarters wants saturation; the franchisee wants survival. The 30,000-store milestone is a zero-sum meat grinder for the local operator.

The algorithm can precisely locate target demographics and physically block their paths. It can use 11.6-day turnover to crush traditional supermarkets. But the algorithm cannot solve its own terminal flaw: when the market inevitably saturates, and everyone has learned the interception trick, the only thing left is a desperate race to the bottom. When the streets are lined with corner stores selling the same cheap bait, location and discounts will no longer be enough to keep the user. The efficiency model will eventually, and inevitably, consume itself.
