In some of the tallest districts of Shenzhen, food orders no longer travel straight from restaurant to customer. Instead, they pass through a new type of worker whose office is a lift lobby and whose job exists only because the towers are just too high.
When skyscrapers create new jobs
China’s major cities have grown vertically at astonishing speed. Districts packed with 40, 60, even 100-storey towers are now standard in places like Shenzhen, Guangzhou and Shanghai.
On the ground, the usual battalion of food couriers races between restaurants and residential complexes. But once they arrive at a mega-tower with dozens of lifts and thousands of flats, the system jams.
In some skyscrapers, a single building can have as many residents as a small town, spread across dozens of floors.
Every minute a courier spends waiting for a lift is a minute not spent collecting the next delivery. When you’re paid by the order, not by the hour, those lost minutes hurt.
Out of this tension, a new figure has appeared: the “relay rider” or “relay courier”, a hyper-local worker whose territory might be just one or two buildings, and whose entire job is to shuttle food upwards.
Who are these “relay couriers”?
Relay couriers sit at the intersection of tech, gig work and extreme urban density. They do not ride motorbikes across the city. Many barely step outside their building.
Typically, they wait in the lobby of a residential tower wearing a fluorescent vest or a platform-branded jacket. As standard delivery drivers arrive, they hand over the orders. The relay courier then handles the “last 50 metres” – or more accurately, the last 50 floors.
- Standard rider: brings the food from restaurant to tower entrance.
- Relay courier: carries the food through security, up the lifts and to the customer’s door.
- Platform algorithm: coordinates both roles and tracks delivery times.
The pay is usually small, often a few yuan per delivery. But the volume can be high in dense complexes where hundreds of orders flow through the lobby each mealtime.

Why the original system stopped working
Before relay couriers appeared, platform riders had to do everything: fight through traffic, park the motorbike, pass building security and then navigate an unfamiliar tower. That meant:
- Long queues for lifts at peak hours.
- Confusing floor layouts and multiple lift banks.
- Security checks in gated communities and office towers.
- Frequent delays and late-delivery penalties.
Platforms use strict timing rules. If riders were held up inside towers, algorithms punished them with lower ratings, fines or fewer future orders. Many riders started refusing orders to certain buildings.
High-rise density turned the last stage of delivery into a bottleneck, pushing platforms to break the job into two parts.
Life inside a 60-storey “delivery zone”
For relay couriers, daily work is repetitive yet intense. Most operate in two bursts: lunchtime and evening, when food apps light up across the tower.
A typical shift might look like this:
| Time | Activity |
|---|---|
| 11:00–12:00 | Waiting in lobby, first orders from nearby restaurants arrive |
| 12:00–13:30 | Continuous lift trips, sometimes carrying 10–15 meals at once |
| 13:30–15:00 | Quieter period, occasional orders, sorting and checking app notifications |
| 18:00–20:00 | Evening peak, heavy flow of family and office orders |
They learn which lifts are fastest, which floors share corridors, and which residents rarely answer the door. Over time, regular customers recognise them and may even prefer a familiar face bringing their food.
Precarious work at high altitude
Despite that sense of routine, the job is highly precarious. Most relay couriers are classified as independent contractors. They receive no basic salary. Their income fluctuates with app demand, building occupancy and weather.
The work itself is physically demanding. Couriers spend hours standing, walking corridors and carrying several delivery bags at once. When lifts are overloaded, they may climb stairs for multiple floors to save time and avoid complaints.
Pay depends on sheer speed: more floors per hour, more orders completed, more chance of staying afloat.
There are also subtle safety issues. Constant rushing through crowded corridors and lift lobbies raises the risk of accidents. Some relay couriers report conflicts with residents unhappy about noisy lift doors, blocked hallways or late-night knockings.
Why China’s towers push the limits
China has more supertall towers than any other country. In megacities like Shenzhen, land prices and planning policies have pushed developers upwards. A single mixed-use complex can squeeze offices, malls, hotels and homes into one site.
At ground level, this vertical growth creates incredible density. Food delivery apps respond with big discounts and ultrafast options, which in turn escalate demand. When thousands of residents order takeaway at the same moment, the building becomes a logistical puzzle.
Standard solutions, such as leaving food in lockers or at reception, meet resistance. Office tenants want hot meals on their desk. Residents expect door-to-door service, especially in high-end towers with premium rents.
Relay couriers become the compromise – a human buffer between the busy street and the private, vertical city above it.
Technology, algorithms and pressure
This shift is closely tied to the way Chinese delivery platforms operate. Algorithms calculate optimal routes and promise speedy delivery to users. They measure performance down to the minute.
Relay couriers are slotted into this system. Their apps assign floors, track movement and sometimes set strict deadlines for handovers. If a rider reaches the building late, relay workers start the job already behind schedule.
Time pressure cascades upwards: a late kitchen, a traffic jam, a busy lift – and the last courier in the chain carries the blame.
Some relay couriers juggle several apps at once, switching between platforms to fill gaps in demand. That can slightly increase income but also raises stress and confusion, as they follow multiple sets of instructions for the same building.
What this says about future cities
The rise of relay couriers in Shenzhen hints at how other cities might adapt as they grow denser and taller. Similar roles could appear where vertical living and on-demand services collide: from Hong Kong to Dubai, and eventually in new high-rise districts in Europe or North America.
For residents, the service brings convenience. People working long hours in offices, or living on the 55th floor with children, gain quick access to food without leaving the flat. For platforms, splitting the route into street-level and tower-level work increases efficiency.
Yet the arrangement also highlights a deeper question: how far on-demand economies can go before basic protections catch up. If a tower depends on a handful of informal couriers to function smoothly, that building’s comfort rests on fragile labour.
Terms and risks worth understanding
Two ideas often appear in discussions of jobs like this: “gig economy” and “platform work”. The gig economy refers to short-term tasks or “gigs” rather than stable jobs. Platform work means jobs managed by apps, where algorithms match workers and customers.
Relay couriers embody both. They accept individual tasks through an app and rarely hold formal employment contracts. That structure brings flexibility but also exposes them to income shocks, lack of insurance and little room to negotiate better conditions.
Imagine a power cut in a 70-storey tower at midday, with dozens of half-finished orders. Lifts stop, mobile signals weaken and corridors darken. In that scenario, relay couriers stand on the front line between panicked customers and unreachable restaurants, with no guarantee of compensation.
On the other hand, the same skills could be redeployed. The knowledge of floor layouts, residents’ habits and building management could support other services: parcel handling, elderly-care visits or maintenance reporting. As high-rise life expands, whole clusters of micro-jobs might form around single buildings, each as unexpected as the relay courier role once seemed.
