That depends on what book you publish. Generally speaking, you send your manuscript to the publisher. However, according to my experience, the publishing rate is generally very low, and unless your writing meets the needs of the current market, most of them will not read it carefully.

In fact, the current network can provide a good operating platform. You can write something on some famous websites online. If dragons are popular, people will naturally come to you. If not, you can take the opportunity to meet many people working in this field and realize that some editors are the best.

Another way is to contribute more, contribute to some newspapers and magazines, and integrate into this environment. It's better to know more people, so that things will be easy.

In short, if you want to publish a book, you should not only have strength, but also create and seize opportunities yourself. This kind of thing is urgent.
