If you want to publish a book, you can follow these steps: 1. Confirm the title, author, publishing house, and other basic information and submit it to the relevant publishing institution or publishing house. 2. Choose a publishing method such as printing, e-book, audio book, etc. Different publishing methods would have different prices and fees. 3. Submit the order and pay the relevant fees such as printing fees, royalties, copyright fees for e-books or audio books, etc. 4. Waiting for publication and earning profits. If a book is published and sold successfully, it will receive royalties. The amount of royalties depends on the price of the book and the sales volume. Under normal circumstances, royalties were calculated based on a certain percentage of sales. The profit earned from each book sold depends on many factors such as the price of the book, sales volume, market conditions, and so on. Generally speaking, if one could determine the price and sales volume of the book and the book was popular in the market, then they could earn a certain amount of profit. However, the specific income would depend on the publishing organization's policies and market conditions.
