In graduation thesis, reference is a very important part, which provides proof of the data source of your thesis, and also reflects the rigor and academic level of your thesis. Regarding the labeling of references, the following rules are usually followed:

1. The format of cited documents must be unified, and generally accepted formats in academic circles can be adopted, such as APA, MLA, Chicago, etc.

2. Many documents of the same author should be marked in chronological order when cited. Such as: (Liu, 2017; Liu, 20 18)

3. For documents with two or three authors, the surnames of all authors can be listed at the same time when tagging in the text. (Wang, Zhang,&; Li, 20 15)

4. For documents with four or more authors, generally, all the authors are written when they first appear, and then the surname of the first author is written with "equal", such as (Ma, Zhang, Li, & Wang, 20 16), and then written as (Ma, etc., 20 16).

5. For periodical articles, the literature notes must contain the periodical name, volume number, issue number, page number and other information. Such as: (Yang, Z, Li, L,&Hu, Wang (20 17). The influence of social media on college students. Journal of Educational Technology Development and Exchange, 10(3), 47-53. )

6. For books, generally, the author, title, publishing house, publication year, page number and other information will be given when the documents are marked, such as (Johnson, B. (20 16). The artificial intelligence revolution is in action. MIT Press. )

In a word, academic integrity is very important when writing graduation thesis, and the annotation of references should be treated strictly to ensure the accuracy of annotation.
