1. Minority literature: This is a relatively neglected field, but it contains rich cultural and historical information. For example, we can study the works of African-American writers, Asian writers or Hispanic writers and discuss their creative background, themes and styles.
2. Feminist literature: Although feminist literature is a relatively mature research field, there are still many problems that have not been fully explored. For example, we can study the historical development of feminist literature or analyze feminist elements in specific works.
3. Post-colonial literature: This is an area that pays attention to the influence and consequences of colonialism. We can study how post-colonial writers reflect and criticize colonialism through their works.
4. Science fiction literature: Although science fiction literature occupies a place in modern literature, it is still a relatively unpopular field compared with realism and romanticism. You can study the theme, skills and influence of science fiction literature.
5. Network literature: With the development of the Internet, network literature has become an important literary form. We can study the characteristics, development trend of online literature and its relationship with traditional literature.
6. Environmental Literature: This is a new field concerned with environmental protection, and we can study the theme, skills and influence of environmental literature.
These unpopular topics have their unique research value and can provide new perspectives and ideas for the study of modern literature.
