Recent edit to Vietnamese people in Hong Kong
Hello, and welcome to Wikipedia. I noticed that you removed some content from Vietnamese people in Hong Kong without explaining why. In the future, it would be helpful to others if you described your changes to Wikipedia with an accurate edit summary. If this was a mistake, don't worry; I restored the removed content. If you would like to experiment, please use the sandbox. 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!

This is your only warning; if you vandalize Wikipedia again, as you did at Vietnamese people in Hong Kong, you may be blocked from editing without further notice. 1989 15:16, 27 April 2017 (UTC)
