quangdieu.com supports learning and reasonable sharing of useful information, but educational content still requires time to research, write, organize and maintain. This policy explains the basic rules for reusing material from the website.
Ownership of original content
Unless otherwise stated, original articles, explanations, examples created specifically for the site, original tables, original graphics and other original material published on quangdieu.com are protected by applicable copyright law. Material credited to another author, publisher, platform or rights holder remains subject to that party’s rights.
What you may do without asking
- Share a link to a public quangdieu.com page.
- Quote a short portion for commentary, teaching discussion, review or another lawful purpose when the source is clearly identified.
- Print or save a reasonable amount of material for your own non-commercial study.
- Refer students or classmates to the original page by link.
What normally requires permission
- Republishing a complete article or a substantial part of one on another website, app, social page, course platform or document.
- Translating and republishing an article in another language.
- Copying tables, lesson structures, original illustrations or collections of examples for a commercial product.
- Using site content in paid courses, books, apps, newsletters, databases or content libraries beyond a limited lawful quotation.
- Scraping or systematically copying a substantial portion of the site for dataset creation, redistribution or competing publication.
- Removing attribution or presenting quangdieu.com content as material created by someone else.
Attribution
Where quotation or reuse is permitted, attribution should be clear enough for the reader to identify the source. A useful attribution normally includes the page title or site name and, when possible, a link to the original public page. Attribution does not by itself make an otherwise unauthorized full copy permissible.
Chinese examples and common language
Individual Chinese words, common expressions, grammar patterns and ordinary facts about the language are not claimed as exclusive property merely because they appear on quangdieu.com. Copyright protects original expression and presentation, not ownership of the Chinese language itself. However, an original selection, explanation, table, lesson sequence, graphic or substantial collection may be protected as a creative work.
Third-party material
The website may occasionally quote, embed or refer to third-party material for teaching, review or reference. Such material remains the property of its respective rights holder and may be subject to separate terms. Permission to reuse quangdieu.com content does not automatically grant permission to reuse third-party material contained in the same page.
Reporting suspected infringement
If you believe content on quangdieu.com uses your protected work without appropriate permission or legal basis, please contact the site in good faith. Include identification of the protected work, the page containing the material, the specific content at issue, your relationship to the rights, and a reliable way to contact you. A clear report makes it easier to review the concern promptly.
Requests to license content
For permission to republish, translate, syndicate, include content in a course or product, or use a substantial amount of material commercially, contact quangdieu.com before publication and describe the material, intended use, audience, format and whether the use is commercial. Permission may be granted, limited, licensed on specific terms or declined.
