In Shenzhen’s dense forest of high‑rises, a strange new job is quietly spreading: delivery workers who only serve other delivery workers. Their mission is simple on paper, and brutal in practice — spending hours every day shuttling takeaway orders from the base of gigantic towers to the dizzying upper floors where residents wait.
Skyscrapers so tall that delivery apps hit a wall
Modern Chinese cities like Shenzhen, Guangzhou and Chongqing have redefined vertical living. Entire neighbourhoods are made of 40, 50 or even 70‑storey residential blocks, packed tightly together. Millions of people live in these towers, often ordering food several times a day through apps such as Meituan or Ele.me.
Delivery platforms promise speed. But that promise usually stops at the entrance hall or the security gate. Guards, gated compounds and strict access rules slow down riders, while each tower can have multiple lifts, locked staircases and confusing internal layouts. Spending ten minutes looking for flat 4703 on the 47th floor simply kills productivity.
In the race for ultra‑fast delivery, every minute spent queuing at a lift is a minute not spent earning the next fare.
Faced with these vertical bottlenecks, a new niche has appeared: “relay couriers”, sometimes called “floor runners” by residents. Their job is to bridge the last few hundred metres — and dozens of floors — between the main delivery rider and the customer’s door.
A new middleman in the food chain
How a relay delivery actually works
The system is both improvised and highly organised. A typical chain looks like this:
- The main rider picks up the food from the restaurant and rides to the residential compound.
- He hands over several orders at once to a relay courier waiting near the gate or lobby.
- The relay courier groups the orders by building and floor, then starts a marathon of lifts and stairwells.
- Once delivered, he confirms via phone or messaging app, so the platform can mark the orders as completed.
Sometimes relay couriers are arranged informally through private chat groups. In other blocks they are semi‑official, known by building management and residents, almost like freelance concierges. Either way, they stand at the base of the skyscraper, phones buzzing, waiting for the next batch of brown paper bags.
Why riders are ready to pay another worker
At first glance, the idea sounds absurd: a gig worker paying another gig worker to finish the job. But the economics make sense in such extreme density.
A platform rider might earn more money by completing six restaurant‑to‑building trips in an hour than by personally bringing each order to the 30th or 50th floor. Delegating the “last fifty metres up” lets them keep moving horizontally across the city.

Relay couriers transform skyscrapers into mini‑warehouses: riders drop off at the base, specialists handle the vertical leg.
Payment is usually tiny per order — sometimes the equivalent of a few pence or cents — but it adds up. A fast relay courier, operating in just one or two towers, can race up and down all day, stacking dozens of micro‑fees into a modest income.
Precarious work in a vertical maze
Extreme urbanisation, extreme fragmentation
This new job is a direct product of China’s rampant urbanisation. As land prices rocket, cities stretch upwards rather than outwards. Dense clusters of towers create both astonishing skylines and logistical nightmares.
In such environments, work itself becomes sliced into ever smaller tasks. One person rides a scooter through traffic. Another person handles the final steps through corridors and lift lobbies. The process resembles an assembly line stretched across space.
Yet behind this clever micro‑specialisation lies a harsh reality. Relay couriers generally lack contracts, social insurance or benefits. Many are migrants already living in cramped rooms in or near the same complexes they serve.
The higher the towers rise, the more invisible the people who climb them for a living can become.
The physical toll of climbing for a living
On good days, lifts work smoothly and queues are short. On bad days — rush hour, lunchtime, or during Covid lockdowns — lifts overflow and waiting times explode. Some couriers give up and take the stairs, climbing 20 or 30 floors with bags of hot food.
The work is repetitive and exhausting. Knees and ankles suffer, especially for older workers. Many couriers wear cheap knee supports or carry spare shoes in their backpacks. In buildings where security is tight, they may face constant ID checks and occasional disputes over access or noise.
The hidden architecture problem
Buildings designed for residents, not logistics
Most high‑rise complexes were designed with residents’ comfort and real estate sales in mind, not the intense daily flow of gig workers. Car parks, lift lobbies and access gates rarely anticipate thousands of food orders passing through every day.
Card access systems, facial recognition gates and private internal courtyards create “soft barriers” that slow deliveries without technically forbidding them. What looks like security for residents becomes lost time for riders.
| Design feature | Benefit for residents | Challenge for couriers |
|---|---|---|
| Multiple locked entrances | More security and privacy | Harder to find the correct door |
| High‑speed lifts | Fast travel for residents | Long queues at peak delivery times |
| Access cards and codes | Limits strangers entering | Couriers wait for residents or guards to let them in |
| Huge compounds | Self‑contained communities | Addresses are confusing and time‑consuming to navigate |
Relay couriers are, in a way, an informal correction to this design gap. They learn every corridor by heart, know which lifts break down, and keep mental maps of which stairwells stay unlocked.
Digital platforms, real‑world consequences
Algorithms that rarely see the stairs
Delivery apps calculate routes and deadlines mainly from map distance, not vertical complexity. A 500‑metre journey looks easy in the app, even if it ends with five lift rides and a maze of hallways.
As a result, riders often face tight deadlines and penalty risks. Late deliveries can mean reduced scores or fines. Offloading the final vertical leg to a relay courier is one way to stay within the app’s unforgiving timing rules.
The app sees a dot on a map; the relay courier sees 48 floors and a broken lift.
Platform companies, for now, tend to treat these vertical specialists as background figures. Some building managers collaborate with relay couriers; others tolerate them; a few try to restrict them, citing congestion or security worries.
Where this vertical hustle might spread next
Shenzhen’s relay couriers are not entirely unique. In parts of Seoul, Singapore and Hong Kong, informal building‑specific helpers already assist couriers. New York and London have doormen and concierges who occasionally take on a similar role, but usually as salaried staff rather than gig workers.
As more cities grow upwards and residents rely heavily on apps, this segmented labour pattern could spread. Think of future super‑tall housing in Mumbai or Jakarta, where bike couriers may stop at the podium, handing orders to resident‑level freelancers who specialise in navigating their own towers.
Risks, trade‑offs and possible alternatives
For residents, the system offers convenience: hot food at the door with minimal delay. For riders, it can raise hourly income. For relay couriers, it provides a job where few other options exist, especially for those without motorbikes or licences.
Yet the trade‑offs are stark. Income is unstable. Work injuries are rarely covered. A downturn in orders hits instantly, with no safety net. And because relay couriers operate in the shadows of two stronger actors — big platforms and powerful property developers — they have little voice in shaping better conditions.
Urban planners and local authorities are starting to talk about design solutions: dedicated delivery lobbies, shared parcel rooms on lower floors, or building‑managed staff who handle the last leg with proper pay and protections. In such a scenario, today’s informal relay courier could evolve into a recognised role, closer to a concierge than a disposable gig worker.
For now, though, the reality in parts of China is simple and striking. The same towers that symbolise economic rise and middle‑class comfort have created a new kind of invisible labourer — someone whose entire job exists because the buildings are just too tall for the original delivery worker to handle alone.
