The requirements for the number of words in a book varied with different publishing institutions and different publishing requirements. However, generally speaking, the publication of a book needed to go through many stages of review and approval, including review, editing, proofreading, publishing, printing, distribution, and so on. The requirements for word count would also be different in all these segments. In some countries or regions, the word count requirement for publishing a book was very strict. For example, in Chinese literature, a long novel usually requires millions of words, while in some Japanese comics and light novels, the word count requirement for each comic or novel is also very high. On the other hand, in some countries and regions, the requirements for the number of words published were not so strict or even had very few restrictions on the number of words. For example, some short stories or self-published books might only need a few thousand words or less. Therefore, if one wanted to publish a book, it was best to understand the publishing regulations and requirements of the country or region and try to meet the word count requirements to ensure the quality of the book. At the same time, he could also adjust the word range of the book according to his interests and creative needs.
