Why were there so few similar articles published?

Doujinshi referred to literary works inspired by characters or plots from other cultures or fictional worlds. Although the works of the same people were widely welcomed, they often faced some difficulties in publishing. The following are some of the factors that can cause doujinshi to be rarely published: 1. The copyright issue: Doujinshi is usually based on characters or plots from other cultures or fictional worlds, so it involves copyright issues. The publishing house may need to obtain permission from the original author to publish a doujinshi work. If the original author did not agree, the publishing house might not be able to publish the doujinshi work. 2. Reader boycott: Some readers may be reluctant to read fanfiction because it often involves characters and plots from other cultures or fictional worlds. These readers may resist attempts to incorporate content from other cultures into their own works, which may also result in fewer doujinshi novels being published. Market instability: The market for doujinshi works may not be very stable because they are usually not labeled as specific works of literature. This could cause the publishing houses to be reluctant to publish fanfiction because they might not be able to make enough profit. 4. Cultural differences: Although works of the same culture are usually based on content from other cultures or fictional worlds, they may still involve some cultural differences. This could make it difficult for readers to understand and appreciate doujinshi works, and it could also make publishing houses unwilling to publish doujinshi works. Therefore, although the works of the same literature are very popular, they face some difficulties in publishing.
