Hello, I'm EN-Jungwon. An edit you recently made to Nathan Evans (singer) seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. 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. EN - Jungwon  09:28, 16 March 2021 (UTC)

Welcome to Wikipedia. We appreciate your contributions, but in one of your recent edits to Lev Landau, it appears that you have added original research, which is against Wikipedia's policies. Original research refers to material—such as facts, allegations, ideas, and personal experiences—for which no reliable, published sources exist; it also encompasses combining published sources in a way to imply something that none of them explicitly say. Please be prepared to cite a reliable source for all of your contributions. You can have a look at the tutorial on citing sources. Thank you. P HANTOM T ECH (talk) 08:56, 20 June 2022 (UTC)
