Looks like buildings under construction, but residents are trapped?

Like pissing on a burning jungle.

Great example of why fire code in buildings are so damn important, otherwise it's a massive tasks to undertake.
Like, how do the firefighters even begin to tackle this scale of incident?

Unironically if that's the standard approved configuration in HK guideline then the highest authority is the one at fault.
The inspecting officer is just ticking boxes on site according to that.
