Application is different from official document writing. Official documents, also known as official documents, refer to all kinds of practical and standardized documents used by government agencies, mass organizations, enterprises and institutions in handling official business. It is an effective means for people to exchange ideas, exchange information and solve problems. Shen Lun is more like a political essay, such as Han Yu's Ma Shuo, which is an ancient argumentative style, stating the author's views on some social issues. Application is one of the subjects of Chinese mainland civil servant qualification examination. In the civil service examination, by reading the set materials, answering relevant questions, we examine the seven abilities of candidates (reading comprehension, analysis and judgment, problem-solving ability, language expression ability, stylistic writing ability, current political application ability and administrative management ability).

Official documents have a certain writing paradigm and are more stylized. On the other hand, there is more room for self-exertion, and one can expound one's own views on a social problem. However, one can't leave the basic structure of argumentative writing, that is, explaining what is the problem, why to do it and how to do it.
