Wauw China! I’ll never forget you. When you are in China as a backpacker it is easy to travel. Trains, subway, busses and airplanes are good. The local bus is only one or two rmb. The subway is also 2 RMB. The long distance busses are not realy expensive and have good connections. The train is amazing. I prefer the hardseat for the normal and long trips (over 7 hours) and the hard sleeper for the real long distances. The hard sleeper is a bed and is sometimes better than a cheap hostel. I think China is a save coutry to backpack and travel. Hostels are cheap and the staff is nice. They want to help you with everything. Just ask for a note for the bus, train or other thing you need.
10 RMB is 1.30 euro
