Generally, walls of some kind not only separate construction sites from the street, but also provide a space for particular kinds of public discourse on and about Shenzhen. On these walls, development firms announce the future building, private eyes advertise their services, and the rare graffiti artist paints a picture. Construction teams tend the walls around important projects more carefully than they would the walls around lesser projects. Workers regularly touch up these walls, projecting an image of neat, orderly, and respectful construction. Guangdong plants, however, have little regard for edges and flourish even at concrete foundations. Please view these inadvertent blooms at: http://pics.livejournal.com/maryannodonnell/gallery/0000gy09
