I found that this town concentrates on getting as much as is humanly possible out of foreigners passing through the town (most of them to watch over some of the last mainline steam trains in the world).
In three shops, the shopkeeper wanted ridiculous amounts (three or four times the price in Beijing) for things like miantou, a tube of toothpaste, and some juice. Then after a polite refusal to pay that amount, the price cam tumbling down. Then when it came time to add up the purchases, the shopkeeper mistakenly added about RMB50 to a total that should have been around RMB38! Then finally, he tried to short-change me.
I had similar experiences in two other shops. Beware!
What to buy: Buy as little as humanly possible.
I am sure the vast, vast majority of people in this potentially lovely village are honest and wonderful, friendly people. I just didn't meet any of them in 24 hours.
I was especially disappointed because the people in surrounding villages and in Jingpeng, to the west, to be especially friendly and kind.
What to pay: Three to four times the usual rate for anything.
Be very careful, and count your change.
