Even for the same manuscript, different publishers have different emphases, and the editing and proofreading level of manuscripts with different themes is also different. For example, literature and art publishing house, ancient books publishing house, art publishing house, children's literature publishing house, science and technology publishing house, etc. Daily topics have their own emphasis. If they all publish the same book, their understanding of the content of the manuscript and the emphasis of editing will definitely be different.
Even the same manuscript and the same type of publishing house have different editing and proofreading levels. For example, the Commercial Press and Zhonghua Book Company are very strong in the field of ancient books publishing, and their editing and proofreading level is very high, so they can be called experts, which is hard to compare with ordinary local ancient books publishing houses. There must be a difference in the editing and proofreading quality between the two.
In some cases, manuscripts are also different. For example, the publication of a dream of red mansions, the general publishing house probably only has one or two versions, because there is no strength to collect too many resources; A powerful publishing house like People's Literature Publishing House may have seven or eight complete editions. Then, if you choose one of these editions as the basic edition and compare it with other editions, the quality of the book will definitely be better after editing and publishing.
