Many of my classmates and I wrote our graduation thesis online in Guo Tao Daily. I feel that it is well written here, and the writing style is quite good.

1. keywords are words or phrases that reflect the theme of the paper, usually arranged below the abstract, and the font size is different from the text. Generally, each article can choose 3~8 keywords, and multiple keywords are separated by semicolons, which are arranged from big to small according to the extension (conceptual scope) level of the entry.

Keywords are generally noun words or phrases, and in some cases there are verb words or phrases. English keywords corresponding to Chinese keywords should be marked. Chinese comes first, foreign language comes last. Chinese keywords are marked with "keywords:" or "[keywords]"; English keywords are marked with "keywords:". Key words should be selected from the National Standard Chinese Thesaurus as far as possible; Important terms and names of new disciplines, regions, people and documents that are not included in the glossary can also be used as keywords. Keywords should be general technical terms that can cover the main content of the paper. 2. Method of selecting keywords Generally, the method of selecting keywords is: after the author finishes writing the paper, he chooses from its title, hierarchical title and text (high-frequency words and keywords).
