There is nothing wrong with a wandering singer, unless he does something bad and hurts others or society, he is not wrong. Wandering singers are also a profession. Of course, maybe this profession is not known to many people.
Quite simply, we can think that it is difficult for almost all so-called adults to accept this profession, especially our parents, or earlier people, our grandparents and so on. And it's hard to understand how a wandering singer works or what kind of existence it is.
Because it includes our impression, we may have a relatively fixed impression of the wandering singer. For example, in the subway, or in crowded shopping malls, or in places where other people come and go, I feel that I have been singing my own songs. Perhaps the word vagrancy is easy to give people a feeling of rags.
But in fact, most wandering singers are not necessarily in rags, and they may even dress more neatly. No matter whether the wandering singer regards this as a profession or a hobby, after all, many people like singing, and we can't deny it.
On the other hand, wandering singers are regarded as beggars, maybe only a small part. For example, some really desperate singers can only make a living by singing, so maybe only those people will be mistaken for beggars.
Most other people, with the development of our economy, their conditions have gradually improved, so they should not be so easy to live on the streets, and they can support themselves as long as they work hard.
