Hello, I'm BilCat. I noticed that you added or changed content in an article, Shenyang J-16, 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 referencing for beginners. If you think I made a mistake, you can leave me a message on my talk page. Thank you. BilCat (talk) 08:19, 3 February 2022 (UTC)

Please do not add or change content, as you did at Chengdu J-10, without citing a reliable source. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Thank you. BilCat (talk) 10:11, 3 February 2022 (UTC)
