Hello, I'm Materialscientist. I noticed that you added or changed content in an article, 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. If you need guidance on referencing, please see the referencing for beginners tutorial, or if you think I made a mistake, you can leave me a message on my talk page. Thank you.

Please do not add or significantly change content without citing verifiable and reliable sources. Before making any potentially controversial edits, it is recommended that you discuss them first on the article's talk page. Please review the guidelines at Citing sources and take this opportunity to add references to the article. Wtmitchell (talk) (earlier Boracay Bill) 12:31, 10 April 2019 (UTC)

Please stop adding unsourced content, as you did on Yinhe incident. This violates Wikipedia's policy on verifiability. If you continue to do so, you may be blocked from editing Wikipedia. David Biddulph (talk) 13:04, 10 April 2019 (UTC)

Hi, I undid your revision on List of prefecture-level cities by GDP per capita because it did not include citations and significantly changed the figures. Please remember to add citations in order to follow Wikipedia's policy on verifiability. Also, as mentioned before, this is the English language Wikipedia, so edit summaries should be written in English. JoLuMo (talk) 01:45, 11 April 2019 (UTC)
