However, if your original works are novels, essays and other literary works, they may even sell well, and the publishing society will pay you the manuscript fee according to the number of words. According to the National Regulations on the Remuneration of Literary Works Published (1April 5, 1999), there are three situations: one is royalties, and the calculation method is: book unit price × book print or sales volume × edition tax rate; The second is the basic manuscript fee+printing and copying manuscript fee; The third is a one-time manuscript fee.
If the publishing house agrees to publish your book, it will also pay you royalties. The publishing house has the right to wholesale (sell) the book to the distributor, and the income has nothing to do with the author.
