For the contents of the assembly, if the originality of the editor can be reflected in the content selection and institutional arrangement, it can become an assembly work protected by copyright law. For example, when writing a set of test questions, the author of online test questions adopts a layout structure that is not adopted by other test questions in the market, which can reflect the author's creativity and unique choice and design of the content and structure of the test questions. Therefore, even if the written test questions use common knowledge points, this set of test questions can be regarded as a compilation work, thus being protected by copyright law.

The education industry is different from the literature and art field, and the original knowledge is inevitably used in teaching materials, test questions and lecture notes, while the audio and video, lecture notes, test questions and courseware of online courses are often not original, so many people will think that online courses and related lecture notes, courseware and test questions can be used at will. However, non-originality does not mean that they are not protected by law. When these audio and video, test questions and courseware meet the requirements of originality of works stipulated in the copyright law in content, they can be protected by the copyright law, and there is a danger of infringement if they are used without the permission of the right holder.
