I have been to Qingdao a couple of times.
It is a really nice town at the coast in Shandong Province. In the past (1897 - 1914), it was a German colony - and this is the place, where the famous
germanchinese beer
Tsingtao comes from
All over the town you can still see German architecture - especially at the railway station.
The town owns the third biggest habour in the world and is famous for seafood, textiles, houseware electronics and tires.
Also, Qingdao has (I think) 3 beaches. And people say, you can really swim there. Must be truth, I have seen some doing it
And, very important, in 2008 the sailing events are held in Qingdao
So, if you have the chance, go there - it is worth a visit
