Are you sure that’s the sewer? Even in China, the goal of sewer management is to keep things flowing at reasonable cost.
In the US, there are two widespread solutions:
1. The ultimate in cost reduction: a 55 gallon drum out back. When it’s full, someone collects it. It’s far more cost effective to dump your oil in a 55 gallon drum than to dump it in a sink and hope you don’t immediately have to call a plumber to clean up the mess.
2. A grease trap: a not-particularly-expensive device like this:

Are you sure the tricks weren’t collecting oil from drums and grease traps?
I’ve never looked at oil collection in China. But here’s a Wikipedia article showing what looks like 55 gallon drums:

- organsnyder 3y agoGrease traps are required in all commercial kitchens here in Michigan. AFAIK they're more intended to protect the sewer system rather than for day-to-day grease disposal.
- amluto 3y agoI think they’re required in California too. In any case, there are multiple companies that will compete to collect your kitchen grease out of that 55 gallon drum, for free. Maybe they’ll even pay if the kitchen makes enough grease — that mess is valuable! I suspect that most kitchens pay for grease trap service, as it’s more labor and equipment intensive and the resulting extracted crud may be more of a mess than a valuable commodity.

- j-a-a-p 3y ago> Are you sure that’s the sewer? It are always grease traps, but it is the same pipe that is used by the toilet, so I would say it is technically just the sewer. And ss the saying goes: if it looks like sewer, smells like sewer, it probably is sewer :-)
- amluto 3y agoHuh? Why on earth would anyone plumb their toilet into the grease trap? There’s probably some cross-contamination from sewage getting into the grease trap outlet, but that doesn’t mean that toilet waste flows through it. There’s also lots of contamination from people washing their hands, cleaning meat and fish, washing dirty vegetables [0], etc in the kitchen sink. Certainly one ought not to eat anything extracted from the grease trap, but one also ought not to eat anything extracted from the grease collection barrel.
