However, as long as the reader is normal, it can still be judged. Most importantly, if everything you learn is to explain your point of view and writing purpose, that's good. If you just copy it and express the same thing as others without your own creativity, it is really plagiarism.

The same is true of poetry, and it is best to indicate the source.
