Can real people or things and place names appear in online novels?

Real people, things, and places could appear in web novels, but they had to pay attention to copyright issues. When creating online novels, one had to respect the copyright of the original work and avoid using existing characters, locations, and other elements to avoid violating the intellectual property rights of others. If you intend to use existing elements in a web novel, such as character names, place names, etc., you need to first obtain the authorization of the original author or adopt some legal adaptation methods, such as changing the name, geographical location, etc., to avoid copyright issues.
