Hello, I'm Dark-World25. I noticed that in this edit to Hanoi Metro, you removed content without adequately explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an edit summary. If this was a mistake, don't worry, the removed content has been restored. 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. Dark-World25 (talk) 07:22, 6 November 2021 (UTC)

Hello, I'm Adakiko. I noticed that you added or changed content in an article, Hanoi Metro, 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. Adakiko (talk) 07:24, 6 November 2021 (UTC)
