If your novel has been written and you want to publish it as a physical book, you need to submit an application to the publishing house. When you apply, you need to provide both electronic and paper copies of the novel, as well as a publishing plan and budget. The publishing house will usually review the application and decide whether to agree to publish your novel. If you pass the review, they will publish the book for you and provide you with publishing fees and other related expenses. When applying for publication, you need to pay attention to choosing a suitable publishing house and understand their publishing policies and requirements. In addition, you need to understand the pricing and sales channels of the book in order to prepare for the publication plan.
