Counterfeiting, reverse counterfeiting, and impersonation are all popular names for trademark infringement. Counterfeiting and passing off are the same form, which is to use the same or similar trademark without the consent of the trademark owner. In layman's terms, products that use the same logo are fakes, fakes, and impersonations; products that use similar logos are called counterfeiting; of course, products that use the same logo can also be called counterfeiting. Reverse counterfeiting is actually relatively simple. It means removing the original trademark from the product using the trademark without the permission of the trademark owner, then marking it with other trademarks and then re-entering the circulation field. This is called reverse counterfeiting. To put it simply, you buy someone else's brand of product, try to cover up or remove the other person's brand, and then put your own brand on it, and then sell it. This is called reverse counterfeiting.
