Not all papers need polishing. In general, there will be some doctors, brothers and sisters who have published papers and some experienced teachers in the laboratory, and they can be asked to help us retouch and revise the drawings.

If it is your first paper, you must find someone to polish it. No matter how perfect you think your writing is, it's just your own feeling.

To polish a scientific research paper, you must find someone from a related major to help you polish it. If you are only an English major, no matter how high your English level is, it is difficult to guarantee the quality of polished papers, which is why many native English speakers may not be able to write a scientific research paper well.

Before retouching, you can discuss with the retouching organization and retouch a small part of the picture first. If satisfied, you can continue to retouch the map. If you are not satisfied, you can ask for a refund and try to minimize your losses.
