In general, there is no problem, except for the following two situations: 1. After receiving the notice of using the manuscript, it cannot be published or delayed. 2. After giving you a draft notice, you sometimes need to modify 1 times later. At this time, if it is not revised according to your opinion, it may not be released to you. The above situation belongs to a few cases, but they are all within the controllable range. My colleague published a paper in Tao Tao Paper Network before and gave it to him. He delayed payment for a month, and the payment happened just when the magazine was revised and the review was strict. His article needed another 2,000 words to be published, and he added another 2,000 words before it was approved. This situation also exists, so we should follow the advice in time.
