Hello, I'm InvalidOS. I noticed that you added or changed content in an article, Yuan dynasty, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources, or if you think I made a mistake, you can leave me a message on my talk page. Thank you. Invalid OS (talk) 14:18, 7 February 2020 (UTC)
