Taxis are 3 yuan to start, and don't go for more than 8-10 yuan any trip around town. It's a nice alternative to buses during cold days, since the buses can get crowded.
Get ur destination written in characters by someone, and show it to the driver.
Do not scream or jump if the driver does a crazy traffic stunt. And don't wear a seatbelt...supposedly it offends them if you do.
On the street...
Don't be afraid to buy fruit in the market. It's generally safe, just wash it. Bananas are 4 yuan/kilo, apples and oranges are not far off. Don't be surprised if fruit is more expensive here than in the big cities in china...it's harder to get produce here. But it's still really cheap.
Meals: 1 yuan for street food, which again is generally safe, or 5-10 yuan for a good sit down restaurant. (No english menus anywhere except close to the American University here)
What to buy: q
Xinzheng Warnings and Dangers
As in the rest of China, traffic laws are more of a suggestion. And rural china is much worse...the lack of police officers seems to allow people more freedom to drive like maniacs. However, the roads are in great condition, something somewhat strange for a 3rd world country.
Xinzheng Off The Beaten Path
Xinzheng is already off the beaten path. But rent a bike from any of the big bike rental people alongside the road (1 yuan for 2 hours!!!, sometimes less) and just go exploring the city on your own. There's not much to see to the naked eye, but it's real china at it's best (or worst). The villagers will all look at you funny, but for the most part it's very safe. This is a photo of a very ancient pagoda I happened to stumble across as I was biking. (bike in thee bottom right hand corner) ... totally abandoned, totally neglected, and totally AUTHENTIC...very difficult to find in china nowadays.
