My opinion is: we can&;t distinguish between true and false, but we can only say that this is a practical need and an alternative occupation. First, it is said that it is a realistic need because some people may have really come to a dead end. Everyone needs two dollars, which may solve the problems of food and clothing and travel expenses. It takes a lot of courage to ask for two dollars from other people&;s strange eyes. Secondly, it is an alternative profession because as long as someone gives it, someone will want it, and some people have regarded it as a career to increase income.
