Two corrections:
1. The book linked above was NOT published as a result of CHP's 2008 survey. It was conducted around the same time in 2008 but was done by a few government agencies: 北京建筑工程学院(Beijing University Of Civil Engineering And Architecture), 北京市城市规划设计研究院 (Beijing Municipal Institute of City Planning and Design) and 北京市规划委员会 (Beijing Municipal Commission on Urban Planning). CHP's results were published as two reports as part of their Friends of Old Beijing project (Phase I Report & Phase II Report can be found here )
2. In the photo above, Rosie is standing in 交道口北三条 hutong, NOT Wudaoying.
Both were mistakes on my part. Apologies for the misunderstanding.
