Some changes have been written above. I attach the revised full text below:
This year's Olympic Games has finally come to a successful conclusion and entered what the media called the "post-Olympic era". These days, many newspapers are reporting the names of Olympic athletes whose names have become registered trademarks. I think the most unfortunate example is Dānlín's "Dānlín" and "Dānlín's name has now become a Panamanian trademark", which has been repeated many times by news broadcasters. I bet Dānlín will be very upset if he hears the news.
Now this article reads much more smoothly and there are no grammatical mistakes. You can refer to it
If you answer yourself seriously, please ask questions and hope to adopt them in time. Thank you.
