To publish a book, some conditions had to be met, as follows: [1. Press: You need to find a press to publish the book.] You can search for information about the publishing house online or contact the editorial department of the publishing house. Usually, the publishing society required the author to provide a topic selection report, an outline, a manuscript, and other materials for the book to be reviewed, edited, and typed before finally deciding whether to publish the book. 2. Transfer of copyright: If you want to write your own book and publish it, you need to transfer the copyright to the publishing house. This could be done by signing a copyright transfer agreement with the publishing house. 3. Print and distribution: Once a book is published, it needs to be printed and distributed. He could contact the printing house to print the book, or he could print the book himself and sell it online. It was possible to write a book and then publish it, but there were other conditions that needed to be met, such as having sufficient writing skills and publishing experience, as well as being able to pay for printing and publishing costs. In addition, he also needed to understand the relevant laws and regulations to ensure that the contents of the books were legal and avoid possible legal risks.
