I'm not sure if there's a thread for this.
Where's a good place, that's not too far from Beijing, where my wife and I could go on vacation for a week? We're open to both resorts (on beaches and the like), or a cool sigutseeing/touring area (with kosher food is a plus).
Thanks
May I suggest something called Google?, I have heard there is a type of a wall, perhaps it is even great, which seems to be near Beijing.
I'm not sure if your are being serious on the beach resort thing, a simple map might show that Beijing is actually pretty darn far from water and pretty darn North!
If you are looking for resorts, Sanya island is the best in China, no clue on internal flight prices, check CTrip or equivalent.
