Is it better for a novel to write about life experiences with empty characters or not empty?

It was a subjective question whether it was better to write about life experiences in a novel by making the characters virtual or not. It mainly depended on the theme and style of the novel. If the main theme of the novel is to describe the life experience and growth process of the character, then you can consider the virtual character. By describing the life experience and encounter of the character, you can shape the character image so that the reader can better understand and feel the character's personality and psychology. If the main theme of the novel is to describe the complexity of social reality and human nature, then it can be considered not to empty the characters, but to reveal the nature and laws of human nature through the actions and decisions of the characters instead of simply describing the life experiences of the characters. When writing, you can decide whether to make the characters virtual or not according to your own theme and style. No matter which method you choose, you need to pay attention to the shaping of the character's personality and the idea of the plot to attract the reader's interest and emotional resonance.
