Doujinshi refers to the act of creating, adapting, or recreating an original work in a unique way. In terms of copyright, whether or not a doujinshi was legal depended on the circumstances. According to intellectual property law, the rights and interests of an original work belonged to the author himself, while doujinshi was a second creation based on the original work. Therefore, under normal circumstances, the copyright of the same person did not belong to the original author but to the doujinshi author or the person who adapted it. Therefore, if a doujinshi wasn't authorized by the original author or the original author wasn't mentioned, it could be an act of copyright violation. However, some authors or companies who were aware of copyright protection might take legal measures to protect their copyrights. In addition, the copyright issue of Doujinshi might also involve the protection of cultural property rights and the "fair use" in intellectual property law. Whether or not a doujinshi was legal in terms of copyright depended on the specific circumstances. If you didn't respect the rights of the original author, it could be an act of copyright violation.

The copyright law refers to the law that grants copyright to literary, artistic, and scientific works. The copyright law was a law that protected the rights of the creator of a work to the intellectual results of his creation. On the computer network, copyright law and copyright law both play a vital role. The copyright law protects literary, artistic, and scientific works on the Internet. The copyright law protects the right to distribute these works on the Internet. For example, publishing novels, poems, essays, and other literary works on the Internet required compliance with copyright law. If these works were protected by copyright law, the author would have the right to modify the work, to grant others the right to use it, to receive remuneration, and so on. At the same time, the spread of literary works on the Internet also needed to abide by copyright laws. If the work is not protected by copyright law, there is no need to bear any legal responsibility. However, if the works were protected by the copyright law, the communicator had to abide by the relevant provisions of the copyright law and bear the corresponding legal responsibility for the violation. Therefore, protecting the rights of literary, artistic, and scientific works on the Internet required compliance with both copyright laws.

The differences and connections between domestic copyright owners and foreign copyright owners are mainly reflected in the following aspects: 1. The nationality of the copyright subject is different: the nationality of the copyright subject in China is China while the nationality of the copyright subject in foreign countries is foreign. This meant that the copyright of authors in China belonged to China, while the copyright of foreign authors belonged to the government or copyright collective management organization of that country. 2. The ownership of copyright is different: Chinese law provides that the copyright is enjoyed by the author himself, while foreign law provides that the copyright is enjoyed by the creator of the work. That is, the author enjoys the copyright but the copyright of the work can be shared by the co-owners. The term of protection of copyrights is different: the term of protection of Chinese copyrights is 20 years, while the term of protection of foreign copyrights is longer, usually 50 years or more. The main qualifications of copyright are different: Chinese law states that only individuals or organizations with certain conditions can be granted copyright, while foreign laws state that anyone can be granted copyright. Although there are differences between Chinese and foreign copyright owners, the relationship between copyright owners is very close. In China, the relationship between copyright owners is usually managed and coordinated by copyright collective management organizations. In addition, copyright owners could also cooperate to create and share intellectual property.

Ancient China did not have a copyright law because the Chinese legal system had already been formed as early as the Spring and Autumn Period. The copyright law was proposed by the European Enlightenment philosophers in the early 20th century. The copyright protection of literary works in ancient Chinese laws mainly relied on the copyrights of ancient poems, Fu, and other literary works such as The Book of Songs and The Songs of Chu. These works already had intellectual property rights when they were created, so the author's copyright was protected by the law at that time. However, the ancient Chinese law did not clarify the ownership of the copyright of literary works like the modern copyright law. During the Warring States Period, some vassal states had a vague treatment of the copyright ownership of literary works, which also led to some disputes about the copyright protection of ancient Chinese literary works. In addition, ancient Chinese laws did not provide sufficient protection for the copyright of literary works. In most cases, the copyright of a work would not be protected by law, and the rights and interests of the creator might not be fully protected. Therefore, although there were some copyrights of literary works in ancient China, due to the lack of clear legal protection, these rights and interests were not fully protected.
