Structural modular with offsite prefab, for sure, but I don't know any specifics on the Wuhan hospital builds. From some other coverage, the units appear to have ISO corner castings, but the proportions don't look like 'normal' containers. There are other proprietary connectors for volumetric prefab - like Z Modular's "VectorBloc" - but these don't seem to be using anything fancy.

What stands out to me, watching the time-lapses: SO. MANY. WORKERS! They are everywhere on site, moving constantly, and the equipment never sits still either. That workforce, along with the certainty that zoning and environmental impacts weren't even a question mark show what the "command" side of a hybrid economy can pull off.
