Tin foil hat time or maybe should I say copper foil? If the sulphurous stuff was “domestic” drywall, is this what the Chicoms get installed in the homes of their enemies?

Chinese residential construction is almost all bricks and mortar, because Chinese labor costs are low, whereas materials costs are basically the same worldwide. In fact, the labor value-added is what accounts for the difference in materials prices. US labor costs are probably 10x Chinese labor costs, whereas US materials costs are maybe 1.5x Chinese materials costs.

I suspect low grade Chinese drywall might be used in private Chinese commercial establishments, including both service and manufacturing sectors. Most private Chinese businesses are intensely price-competitive and therefore have a here-today-gone-tomorrow flavor that does not encourage the building of monuments, meaning a lot of structures are built with the cheapest possible materials. State-owned companies probably use the better product, since they are (1) less profit-driven and (2) the beneficiaries of both government-granted monopolies and routine interventions to prop them up if their finances are looking sickly.

Most Chinese businesses don't have HVAC systems on 24 hours a day, so bad drywall may not be such a problem. I suspect the remedy for anyone with bad drywall may be to turn off the HVAC system and open the windows at least 8 hours a day.
