Right, the way you how you approach and ask those people are quite important to know their demand and what they really want. I will try to figure out how they sleep and how they view the way of having a "roof" or a "blanket", maybe the homeless in China prefer a blanket rather than a roof because they don't get used to a roof. Anyway, let's see how it would be and I will keep updating.
Thank you for your comment and support. I appreciate your idea but could you please explain the concept of economic or sustainability circle in details or giving some examples? I think as a Grind-Material-Made sleeping bag, all the materials are green and reusable. However, you have mentioned me, if the homeless and refugees reject our product or it was not used in the right way, how do we deal with these sleeping bags? @Anne-Laure professor do you have any ideas?
I as myself are thinking about interviewing some homeless in Beijing, China as to see if it works for them. I think there must be some common points and different ideas between the NY homeless and China homeless, maybe we could find something new to improve our prototype?
