A one week travel in China.
Me and two friends managed to stick a one week trip to China during the Halloween period. One of them lived there several years so he led us quickly to the hot spots. We got to see so many things in such a short period of time that the trip seemed actually much longer.
A really good part of having someone who lived there was that we didn't just see the touristic places, but we also hung out with people and in places that we would have never seen otherwise.
