On a main road in downtown New York, there is such a newsstand. There are a variety of well-known domestic newspapers and magazines in the newsstand. In the morning, nearby office workers like to buy a morning newspaper from here. In the evening, many pedestrians who come out for shopping and shopping also like to buy a evening newspaper from here, and then leisurely spread out on the bench next to the street.
What I want to explain here is that the owner of the newsstand is a blind person who has spent a year. Maybe you have to ask questions: Can blind people sell newspapers? What if someone else lie to him?
As it turns out, these questions are completely redundant.
