From Wikigogy

are links along the top of the page to geographical location. See Hangzhou for how it really looks. Example wikitext for breadcrumbs:

[[Continent]] : [[Country]] : [[Province]] : [[City Name]]

If you are not sure what the geographical bread crumbs for your city should look like, try cutting and pasting the bread crumbs from the top of the Wikitravel.org page for your city as a start. Type the name of your city into their search box to get to it.

Just add the double square brackets [[ ]] as needed to make the breadcrumbs Wikigogy page links.

And if the pages don't exist yet, don't worry. Put something on them or let someone else do it. The links still indicate where your city is and that is helpful, too.
