Have you ever ask something on StackOverflow and someone flag your question as duplicated but he doesn't know what your question is really about! 😒😊

Or, you even mention the other question and point out how yours is different and that answer can't help you, but still just get *flag**flag**flag**flag*

@kaqqao Thank you so much,but I deleted. Due to commenting so much on the post and argue with that person. I asked something about Mongo DB and Python. He didn't know what the Document class is in the mongoengine package. And answered me wrong and also flag my question as duplicated and made me so angry those days...
But Thanks a lot!
