Why did Hitler come to Vienna on 1909, which was the saddest period in his life?

1909 Hitler came to Vienna alone and began the saddest period of his life. In the previous five years, because of his father's death and family restrictions, he has been dropping out of school and dreaming of becoming an artist. At this time, 20-year-old Hitler was wearing a black coat that was given to him by a Hungarian Jewish second-hand clothing dealer, reaching his ankles. The hair on his forehead is combed obliquely, and his head is messy. Wearing a greasy shiny black hat, the seasons are the same. With thick beards on his cheeks and chin, he wandered from street to street with an old easel on his back, drawing some poor Viennese paintings. There are paintings of St. Stephen's Cathedral, Opera House, Berg Theatre and Sch? nbrunn Palace. , sold to vendors to decorate the wall, sold to businessmen embedded in a picture frame for display and sale. Or bought by furniture manufacturers and nailed to cheap sofas and chairs. Buy some cheap food in a small hotel or waiting room with the money from selling paintings during the day, and spend the night on a park bench or at any door at night. Even in an emergency, he pawned his clothes until there was nothing around him, and finally joined the homeless team who lived on porridge and received charity.
