What do you mean by a secondary house?

Secondary residence refers to the type of residence that has enthusiasm for the secondary world (that is, the "two-dimensional plane world"), such as comics, movies, comics, photography, novels and so on. ). Because of my passion for my hobbies, I neglected people or things in reality. Because not everyone in China understands the connotation of the second world, and even it is quite exclusive, such people are often regarded as weirdos.
