Poor Old Man

I am not sure others realize that there are many senior citizens are collecting recyclable trash in the city. They normally picking polymer containers, papers, cartons, aluminium or other metal stuffs. Some would carry along by hands, some use trolley or tricycle. It seems they are consistently doing it. All these trashes could only bring them very tiny earning, which tells us they are most probably living in very poor and difficult situation. This reminds me of the scene that I published 2 years ago and the same question shall be asked.
