Metalwork at Jinwuxing. I think it stainless steel, although I’m not really sure.
And, yes, the sky was that blue.
I needed to get an assortment of stuff (such as hinges, a door threshold, custom-cut metal plates, and wood shelves), so I went down to Jinwuxing yesterday. Fairly devoid of tourists (and, by that, I mean both the foreign and Chinese types), it is one of the places that makes Beijing home for me.
