Hello, Theanonymity.de! Welcome to Wikivoyage.
To help get you started contributing, we've created a tips for new contributors page, full of helpful links about policies and guidelines and style, as well as some important information on copyleft and basic stuff like how to edit a page. If you need help, check out Help, or post a message in the travellers' pub. New users are also welcome to post any questions or concerns to the arrivals lounge. If you want some practice editing, please do so on our graffiti wall. If you are familiar with Wikipedia, take a look over some of the differences here. If you want to contribute with information about the place where you live, see Wikivoyage:Welcome, locals.
Firstly, thanks for working on the Xi'an article.
I noticed you added a link to a Wikipedia article, please check out what Wikivoyage:Links to Wikipedia#In-line links says: Wikipedia and Wikidata are now standard fields in all Wikivoyage listing templates. Links to the relevant Wikipedia and Wikidata pages should be added to these fields in listings whenever possible. Inline links to Wikipedia are otherwise generally not used in mainspace pages on this site, to avoid their being mistaken for internal links to other Wikivoyage articles. See Wikivoyage:External links. --Ypsilon (talk) 19:21, 3 August 2021 (UTC)
