The length of a novel usually depended on how it was published and serialised. In terms of publishing, the length of a novel was usually decided by the publishing house and the publishing company, not the author. Some publishing houses may require a novel to reach a certain number of words before it can be published, while others may allow the author to freely control the length of the novel. The length of the serial novel also depended on the wishes of the author and the bookstore. Under normal circumstances, the author could choose to serialize the novel to a certain number of words or to have no limit at all. The length of the novel depended on the reader's reading speed and the development of the story. If the novel is too long, the reader may get bored or lose patience, but the short story is more likely to attract the reader's interest. As for why the 130,000-word novel was a medium-length one, it was probably because the story had developed a lot and needed to be further developed and narrated. At the same time, the length limit of the serial novel might also allow the author to make a short ending under this word count so that the story could continue to develop. On the other hand, publishing novels usually required longer content to allow readers to understand the plot and characters more fully.
