Fan creation platform. Ao3, also known as Ao3, is a fan creation platform and a non-profit website. The interface is in English, and the collected works include fan fiction, fan paintings, fan videos and audio novels (fan culture refers to the carrier of re-creation by using elements such as characters, storylines or background settings in original cartoons, animations, novels and film and television works). Ao3 is different from many novel platforms in China. ao3 is a "vegetarian" and is ridiculed by many users as a "parking lot". However, the platform is very detailed about the content of the article, including whether it is suitable for minors to read, whether there is violence, whether there are main characters dying, etc.
