So, I'm a little hesitant to link to this user because many people get fixated on her personal style, but reddit.com/u/sexycyborg is a maker based in Shenzhen who frequently posts about the markets there. Her projects are also an example of what end users are doing with the good they are getting in these markets and the kind of innovation it can inspire
It's quite long, but a fascinating look into a part of the world I didn't know existed. A hopeful notion of where the maker movement and open hardware might go. I'm jealous that there isn't something similar close by.
