Pingyao is declared World Heritage by Unesco. The city remained the same since the Han dynasty, so you can get a taste here of what old China was like.
The banking in China started here, so you'll find a quite old Qing dynasty bank/museum.
There are city walls around the entire city, which withstood the time quite well. Also some temples in the neighborhood.
You can get a combination ticket for the various places of interest in the tourist booths. Take a student card (random card which says student & has your pic) to get a good discount.
I found some hostel representative at the train station, the hostel was quite nice & the room came with bikes for everyone. Quite handy to move around, and you can ride to some nearby monasteries. Ask for a map in the hostel.
You can withdraw money just outside the old city walls, there's an int'l bank there.
