Paper retouching companies are generally reliable, but we also need to recognize the fact that we must absolutely keep our eyes open, be responsible for our own papers and not be careless. Still depends on the curative effect, not the advertisement. Many retouching companies have made their websites very professional, and even put the logo of many universities and research institutions on them, which is obviously very tall, but these are false and contrary to business ethics. Some retouching companies even invite Indians to retouch. Another thorny issue is the field of retouching. It can be said that the research field of this subject is very extensive, but the retouching editors in this field can't cover everything, so it is necessary to find out whether the company has editors in this field before retouching. If not, please make a detour. The polishing institutions recommended by the publishing house are basically reliable and can be used with confidence.
