It is time for another one of these pretty doors. As most of them it is very abused and used. Weeds are doing just fine on that roof as well, I wonder how old it is. I don’t think anyone lives there, it looks more like some type of local government or maybe some type of utility company office. I would translate those signs but don’t have dictionary handy at the moment.
Anyhow, this is #6 in this short series of Red Doors, if you want to see details and translate some of that Chinese you can just click on the image to open it my art gallery at much higher resolution. You can also see other Red Doors if you look under Beijing category on the right.
