Long walk through the Hong Kong Brutalist Estates

Hi guys, I am travelling to Hong Kong in the period 17-24.04 and would love to discover Hong Kong off the beaten tourist path. I get overly excited about modernist and brutalist architecture and the city has no shortage of that! I love to walk and discover by foot residential neighbourhoods bustling with life and see how the locals live and go about their daily activities. I have attached a map of the housing estates that I want to visit (Tsui Lam estate, Ping Shek estate, Nam Shan estate, Shek Kip Mei estate, Mei Foo Sun Chien and others) and would be extremely happy if I find like minded people who enjoy walking and admiring the urban scenery!
