The definition of plagiarism was to directly or indirectly borrow or apply other people's works, thoughts, opinions, language, and other elements to form a part of one's own work. In the field of novels, plagiarism usually referred to the plot, characters, scenes, and other elements of the novel being similar to other people's works, or even directly borrowing the words or voices of other people's works. If the plot, characters, scenes, and other elements of the two novels were highly similar, then it might be considered plagiarism. In this case, the reader might feel that the plot and the characters are similar, and even the entire world structure is similar. These may constitute plagiarism. Of course, it was also allowed to borrow other people's works in the process of writing a novel, but the source had to be indicated. If the work was a well-known work or involved copyright issues, then they needed to pay attention to avoid plagiarism. Plarism was a serious creative problem. It not only damaged the rights of the original author, but also had a negative impact on the readers. Therefore, novelists should always pay attention to avoid plagiarism and respect intellectual property rights to create excellent works.
