Literature is literature, and the introduction is generally the opening of the paper. If it is a five-paragraph article, the first paragraph is an introduction. Literary words include novels and essays, mainly literary words, such as Jane Eyre and Pride and Prejudice, which can all be called literariness. The writing method of the introduction should be clear and clear, and in this paragraph, you should show your own views to the readers, and also list the arguments (mainly used for argument). In some prose-style articles, the introduction should also include your own writing background and purpose, etc ... In short, these two things are not the same (the answer is a bit confusing, sorry).
