If a copy is a simple copy of the original, no matter how it is copied, it is only a copy of the original, and it does not contain originality. It cannot be counted as one's own work and cannot be protected by copyright law. If the copyist adds his own personalized and original elements on the basis of the original work, so that the copied work has different substantive changes from the original work, then the copied work can constitute a new work and also a deductive work of the original work.

Artistic copying is a means, but it is not the basis of artistic creation. If a person constantly plagiarizes in artistic creation, then his artistic works without personal style are always copied repeatedly, and without innovation, they will be regarded as imitation and plagiarism by people, and will be abandoned by the market and people.
