If the pen name has been repeated with someone else, you can consider the following methods: 1. Change pen names. Choose a more unique name to avoid repetition. 2. Use traditional Chinese. Traditional Chinese was the official language of Taiwan and Hong Kong. Many websites would not identify authors who used traditional Chinese. Therefore, using traditional Chinese may be more acceptable to the website, but you also need to pay attention to copyright issues. 3. Change some words in the pen name. You can replace certain words in your pen name with other words to achieve a different purpose from other pen names. If you can't use traditional Chinese characters on some websites, you can try using simplified Chinese characters. Some websites might only support traditional Chinese, so it might be more appropriate to use simplified Chinese. However, please note that using a different font may cause the website to not recognize the pen name. You still need to consider it carefully.
