When I was in Shenzhen and Guangzhou, I often wondered how a handicapped person managed to go across those main streets since both sides of the sidewalks were blocked off by barriers to prevent pedestrians from jaywalking. Even each end of the block was fenced in. Obviously a handicapped person cannot not drive his wheelchair up on to the sky walkways but on the other hand, I failed to find any escalators or elevators nearby (like we have in Hong Kong).
