Still Have Questions About the System for Uploading Works

This is my first time uploading a novel on this platform, but I still have questions about how many words I need to upload. I only plan to write short stories, but looking at the mess, sometimes 3k words, sometimes 6k, sometimes 1w2, I don't know where to ask. I want to try asking in this way and see if it can pass the review. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
