Beijing itself is sprawling. There doesn't seem to be a city center, and because of the grime on the building walls from the pollution, it can seem to be not so nice. But don't be misled - there are many beautiful spots in Beijing. Portions of the Great Wall of China can be reached within half an hour's drive, and the Temple of Heaven is stunning with its grandiose symmetry and is without a doubt the best place to people-watch in China - we saw people playing hacky sack, ballroom dancing, painting calligraphy on the tiles in water, and playing the erdu. It was like an instant immersion into the culture.
Quick Tips:
If you can, have someone in your group who speaks Chinese. This is a major help. The hotel’s staff seems to know the basics and generally have an English dictionary at the desk, but we often had to resort to pantomime if our guide was not around.
When shopping from stalls, it is expected for you to haggle. A good rule of thumb is to offer about a third of what is asked, then mutter "too expensive" when the vendor counters and start to walk away. This will bring the price down, and vendors seem to enjoy the interplay.
Best Way To Get Around:
Do NOT drive yourself!!! The Chinese seem to have a very fluid sense of traffic laws, i.e. they can scare you witless, make five lanes out of three, etc. For the same reason, crossing the street while walking can seem hazardous as well - only cross when you see other Chinese people crossing.
