I very happy！ my country make new things！i think make a special lane of the sidewalk for     people using phones. Prompt people walk don't use phones.
          Using phone online facebook，weixin,QQ. these is very Danger walking using phone. some time using phone walking at Street .but you can't see the road line.you already rush the red light.
         So i think we need make sidewalk for people using phones.remind people don't at street using phone online.i hope America can make sidewalk for using phones.
