Conciseness of language expression is one of the most important principles when writing a thesis. But conciseness does not mean simplicity and rudeness, but expresses clear and accurate content in a concise way to avoid lengthy and complicated narration.

Here are several reasons why language expression should be as concise as possible when writing a paper:

1. clearly convey information: concise language helps to clearly convey the research contents, opinions and conclusions to readers and reduce the possibility of ambiguity and misunderstanding. This will help readers understand your argument more quickly.

2. Improve reading efficiency: Papers are usually read by professionals, peers and reviewers. Using concise language can improve reading efficiency and save readers' time and energy.

3. Emphasize key information: In the era of information explosion, people's reading attention is limited. Using concise language helps to highlight the key information in the article and makes it easier for readers to grasp your argument.

4. Enhance readability: Long sentences and lengthy paragraphs may make readers feel confused and tired. Concise language can enhance the readability of papers and make readers more willing to read in depth.

5. Conform to academic norms: academic papers need accurate expression to avoid nonsense and redundant rhetoric. Concise language helps to ensure the rigor and academic nature of the paper.

However, while pursuing simplicity, we should also pay attention to avoid oversimplification leading to inaccurate or incomplete information. Some complex concepts may need to be explained in more detail to ensure that readers can fully understand your point of view. In addition, appropriate background information and argument support are also important parts of the paper and should not be omitted because of the pursuit of brevity. Therefore, on the basis of keeping concise, we should also give consideration to the integrity and accuracy of information.
