Recent edit to Lee Won-keun
Hello. I noticed that you made an edit to a biography of a living person (Lee Won-keun), but that you didn't support your changes with a citation to a reliable source. Wikipedia has a strict policy concerning how we write about living people, so please help us keep such articles accurate. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you! Materialscientist (talk) 09:51, 11 May 2019 (UTC)
