Fiction:
* Historical fiction: This is perhaps her most well-known genre, particularly her novels set in China, like "The Good Earth" and "Sons." She explores themes of family, tradition, and cultural change in a historical context.
* Literary fiction: Her novels often delve into complex character development, social commentary, and psychological insights.
* Romance: Some of her works feature romantic relationships, but they are often interwoven with other themes and not the primary focus.
Non-Fiction:
* Autobiography: Buck wrote extensively about her own life and experiences in "My Several Worlds" and "The Child Who Never Grew."
* Memoir: She also wrote memoirs about her family, her work, and her travels.
* Essays: She frequently published essays on various subjects, including literature, culture, and social issues.
Other:
* Children's literature: She wrote several books for children, including "The Big Wave" and "The Chinese Children Next Door."
It's important to note that: While Buck's work is primarily categorized as fiction, many of her novels blur the lines between fiction and non-fiction due to their historical accuracy and insightful commentary on social issues.
