✍️ Originality requires independent creation, which basically means the work cannot be copied from another work. This does not mean that the work has to be particularly novel or unique. Two very similar works based on the same underlying idea or concept may each have copyright protection as long as one was not copied from the other. Authors may also create works based on other authors’ works, such as translating an English novel into Chinese, or turning the novel into a film. If the original work is still in its copyright term then permission is needed before undertaking translations or adaptations. To be protected and considered original, works must also display some degree of creativity.
