Good morning!
I've downvoted my post so I'll leave a comment.
I know the intention of downvoting, but this article is not a copy of someone else's post, but a post on my own Naver blog. In other words, this is my writing(see below link).

Thanks for reading.
you should post first on steem then write on your own blog. In this way you will not receive any downvote.
