I would like to visit your nice country in 7days from North to South?

Actually, it is a little hard to well code your trip from North to South. As for your case, you'd better turn to a tour company, which may arrange all on the severn-day trip according to your requirements. I recommend TravelChinaGuide.com to you. It can surely make a very detailed and considerate plan for you. Here is their email address: tourstravelchinaguide
