1, there are still certain economic conditions, because the sales of many books are not very optimistic, so you should be prepared to lose money, and there will be a series of activities later-who will bear the expenses?

2. Either your book has a selling point-it sells well and the publishing house is willing to cover it all-this seems to be easier to handle-but there are very few books that sell well now-

3, at your own expense, but I'm afraid even if someone is willing to buy this book for you-but when it will be sold out and when it will be settled-this is unknown-4, many authors, in order to fulfill their dream of publishing a book, still give themselves an account, or look forward to the change of fate after publishing a book-don't expect too much-unless your book is very good and there is a better one in a certain field.

Either you finish this book and give it to your friends. People may not read it-of course, the rest will stay at home. Every time I see it, I have a complicated feeling. ...

I'm not optimistic because this is a common phenomenon-you can pay attention to the print run of published books, and you will find that books are not optimistic, and publishers have been in this industry for many years, and what books sell well is not-is still sensitive. ...

I am not a professional. Let me give you a reference.
