When someone else copies the content of your article, a copyright notice is automatically added at the end of the article. Network copyright awareness is weak. This is a gentleman's practice. If you really want to copy your article, it will be useless to declare more. Just like the declaration at the bottom of my website, it is almost a decoration, I also read it. The article reserves all rights. If you copy my article without following my statement, maybe I will chat with you someday ......
