Does the teacher refuse to upload VIP papers before uploading them?
Yes, but if you don't pass the census, you need to modify the red part of the census before checking again. It is necessary to clarify the submission requirements of the final version of VIP. The final process of Wip is generally as follows: the author submits the manuscript, and after editing and checking, it is sent back to the author for revision, and the author resubmits the manuscript after revision.
