The first way: contact the publishing house and publish the book at your own expense. It costs a lot, and basically no one buys it, or no one buys it, because no matter how good or bad your writing is, no one is famous and no one is speculating on you, it is definitely not acceptable;
Second, just find a printing factory, cheaper, just print, there is no publishing house. Printed for fun, like pirated books, it can be given to relatives and friends.
