Homeless in Paris and London - George Orwell

In travel notes or diaries, Orwell conveyed to us the life of an English vagabond between Paris and London. As if he presented a comparison between the vagabond in Paris and the vagabond in London.. A novel dominated by poverty and misery on every side, and here I raise a number of questions, who is the vagabond? And how does he live? What are the circumstances that led him to live this miserable? What is society's view of him? But how does he view himself? What is the ceiling of his wishes and what dreams?
