Are there any requirements for the things quoted in the novel?

In most cases, a novel is quoted. This is the standard practice in various forms of writing and communication. Underlining is less frequently used for indicating a novel's title.

Citing other people's content in a book had to abide by the relevant laws. According to the provisions of China's "copyright law", when using another person's work, the source should be indicated and remuneration should be paid. To be specific, when using another person's work in a work, the author's name, the name of the work, the publishing house, the date of publication, and other information should be indicated, as well as the source. When you quote other people's works, you also need to pay attention to whether the quoted content belongs to the work in the sense of copyright law. If it belongs to the work, you need to pay attention to the details such as the way of quote and the scope of quote. In addition, when you quote other people's works, you must also abide by the relevant provisions of the personal rights and property rights in the copyright law to avoid violating the rights and interests of others. If the content quoted involves copyright issues, it is recommended that the author confirm the copyright before the quote to avoid possible legal risks.

Quoting from someone else's work when writing a novel was technically not plagiarism because it was legal. Citation is a form of quote that refers to the use of other people's characters, plot, location, language, and other elements in a novel or other literary work without indicating the source of the quote. Quoting elements from other people's works could enrich his own works and increase the literary elements and depth. However, if the content quoted had nothing to do with another person's work or if it completely quoted a sentence or a plot from another person's work without indicating the source of the quote, it might be considered plagiarism. In order to avoid plagiarism, one should pay attention to the source of the quote. If you quote someone else's work, you should indicate the source of the quote, such as "This information comes from XXX" or "I refer to relevant content in XXX". Although it was not considered plagiarism to quote from someone else's work, one should still pay attention to copyright issues in writing to avoid unnecessary disputes.
