Dalian metro Line 2 extended
http://www.metro-report.com/news/news-by-region/china/single-view/view/dalian-metro-line-2-extended.html
When I visited Dalian last month, there had already been signage showing "This platform is for Xinzhaizi", even though all of the trains were bound for Airport, and don't reach Xinzhaizi.
As is often the case with metro in China, signage is renewed, even if extension is scheduled months later.
That's probably because authorites cannot afford to take care of signage, due to frequent extension of metro lines.
