The end of the typhoon shelter wall, is where Johnny Wang goes to ask for help from Yuen Wo-Ping, who is enjoying a spot of fishing. Thank's to Phil from the Hong Kong (& Macau) Stuff / Hong Kong (& Macau) Film Stuff blogs for the super spotting.
There isn't a Street View which captured this spot well, but this Panoramio image shows the end of the wall nicely (thanks to Cheungkkanthony).
