答案：答案:The problem of smartphone focused pedestrians/mobile phone addicts/cellphone addicts/tech addicts is not unique to China. Washington, D.C., the capital of the United States, is the first to set up a mobile phone sidewalk in 2014. The aim was to warn people who have fallen into the habit of looking down at their phones while walking to pay attention to traffic and other pedestrians. Based on this experiment, China＇s first sidewalk lane has been designated in Chongqing specially for mobile phone users. Despite such an innovation, this lane has been criticized for possibly encouraging bad habits and causing accidents. In fact, it is still unclear whether this initiative will pay off.
