The main purpose of official document writing is to highlight the point of view and clarify the main purpose, which is the intention and purpose; An opinion is an opinion or opinion. Any official document has the purpose of writing, and practicality is the basic attribute of official documents. Therefore, it is easy to accept that official documents must have a theme, intention and purpose. However, this is not necessarily the case. Some researchers have suggested that long official documents, such as reports, resolutions, circulars or minutes of special work meetings, work summaries, research reports, etc., are self-evident; Even some viewpoints and basic viewpoints are not difficult to understand. And some short official documents, such as business notices and requests for instructions on something, are often integrated with paragraphs. What's your opinion? Some short official documents, even just a sentence, such as the submitted report, the text is "I will submit (or send) a report on XXX for your review". Can this be said to be an opinion? In fact, whether in the official document, directly in the text, or in the basis and layout, the views are clear. Even if it is a one-sentence report, since it is a "double (joint)" document, materials and attachments must be submitted later, and there must be "opinions"; It is the superior leader who needs to review and must submit according to the relevant regulations, which shows that it is "advocacy". Therefore, no matter how long the document is, the point of view must be clear and the main idea should be prominent. Further research shows that for a long time, people are used to using "theme" and "center" to express the "theme" and "viewpoint" of official documents; The word "viewpoint" is used to study all articles, and "basic viewpoint" is often used to study theoretical articles.
