Cách sử dụng
A pseudonym is a false or fake name that someone uses instead of their real name, often for privacy reasons. People may use a pseudonym when writing books or articles, posting on social media or forums, or engaging in other activities where they want to keep their identity hidden. For example, if someone named John Smith chooses to write a book but doesn't want his real name to be used, he may choose a pseudonym like J.S. Harper instead.
