Having lived in Beijing myself in 2014, most hutongs are not comparable to Indian slums; some might be. But there are definitely problematic housing situations for migrant workers, even now. Many live in dangerous conditions, if not slum-like conditions, though some would consider these to be slums (certainly, many would agree that these properties are run by slumlords). At this point, we are quibbling about the meanings of words, when we should really be focused on whether people can live healthy, safe, and productive lives on their current salaries.

the author say something you'd like to hear then you instinctively think it's logic. Given that this is a complaint I have about many people, it is an interesting feeling to have someone else have this complaint about me.
