Hello, I'm Bmf 051. I noticed that you added or changed content in an article, Hans-Joachim Lang, 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. If you think I made a mistake, you can leave me a message on my talk page. Thank you. Bmf 051 (talk) 13:57, 18 July 2020 (UTC)
