Hong Kong and Its pedestrian walkways
I went to Hong Kong with a mission, and that is to explore all of its pedestrian layers. While researching for my thesis, I became very interested in the layering of urban infrastructures that stack up the city in a vertical fashion. In the extremely dense city of Hong Kong, these elevated and underground pedestrian networks make up a large part of the city's transportation infrastructure, and they facilitate not only safe and conditioned passages but also act as another layer of public space that often hosts political demonstrations and leisurely activities.
If you might be interested in exploring Hong Kong in a similar way, I would recommend looking at this unconventional travel guide--Cities Without Ground: A Hong Kong Guidebook
