I know that China has many great sites but most of the sites before WHS nomination are relatively unknown, that make me wonder are there any international well known site in China that still not be WHS or not even in the tentative list?
How many of the sites inscribed in France or Italy are internationally known before inscription? That is part of the reason why so many places vie for the title in the first place, to get known to a larger audience.
Looking at Germany I feel that easily 25% of all sites are little known. Even to Germans: Lorsch, Grube Messel, Wies, Völklinger Hütte, Brühl, Berlin Modernist Housing Estates, Corvey, Alfeld, Beech Forests, Bayreuth, Muskau ... come to my mind.
