The word "fans" comes from Japanese "どぅじん", which originally means people with the same aspirations and interests. It is a word of secondary culture, which refers to "self-creation, not influenced by business" or "independent" creation. There is greater creative freedom than commercial creation, and it has the taste of "creating whatever you want". Fan Zhi is a self-made publication of this kind of creation. This sector is called "fan sector". This word comes from the Japanese "Tale of the Same Person" (どぅじんしし), which refers to a group of books and publications created and published by the same group of people. Although the so-called fan zhi does not specifically limit the object of creation, for ordinary people, the use of this word is often heard.
