The time taken to publish a book depends on many factors, including the author, the publishing company, the publishing cycle, the speed of printing and distribution, and so on. Under normal circumstances, the publishing cycle of a book ranged from months to years. The authors would usually be rigorously evaluated and reviewed by the publishing company to ensure that the quality of the book met their requirements. After editing and proofreading, the book would be arranged, designed, bound, and printed. This usually took several months, during which time it would need to be revised and proofread many times to ensure the quality of the final book. Eventually, the books would be distributed to various sales channels such as bookstores, online bookstores, and e-book platforms. This process would take months to years, depending on the popularity and sales of the book. Therefore, it took a long time to publish a book, and it also required continuous effort and adjustment to ensure the quality and success of the final book.
