Rio de Janéo and the City of Saints were both fictional novels or movies, so their plots were freely developed by the creators. The theme and plot of these novels or movies are based on different needs and target audiences, so there may be a variety of storylines. Some novels or movies may tell a fixed story while others may tell the same theme in different ways and angles.
The City of Saints in Rio de Janero was a famous novel by Ernest Hemmingway. It told the story of the protagonist, Mallinger, who lived a difficult and lonely life in the City of Saints in Rio de Janero.
Ma Liang was an unemployed bank employee who had been abused by his boss and had embarked on a journey to find freedom and dignity. He met many interesting people in Rio de Janero, including a kind prostitute, a mysterious musician who loved music, and an adventurous traveler.
Ma Liang spent a challenging and thrilling time with these people. He tried to get rid of the boss's control and find his own way out. At the same time, he also experienced the passion and romance of Rio de Janero. In the end, Ma Liang decided to stay in Rio de Janero and established his own life there as an artist.
This story showed Ma Liang's tenacity and perseverance in difficult situations, as well as his pursuit of freedom and truth. It also reflected Ernest's criticism and reflection on Brazilian culture and society.
