Beijing offers every experience one could wish for in a Chinese city. Like Shanghai, it is large, with traffic to suit its population, yet unlike Shanghai, it is openly planned and has an air of space about it.
Clean, with beautiful parks and nature strips, it is not the eyesore one would expect. However, the Olympics is coming up, so I think a lot has been put into preparing the city for the Games, including large screens to hide the shanties. The city has a veil of smog perpetually hanging over it, but surprisingly, the air is not choked with fumes.
Several of China's most famous and intriguing attractions lie in or near Beijing, including Tiananmen Square, the Forbidden City, the Temple of Heaven, the Summer Palace and of course, the Great Wall. Each place is unexpectedly enormous, and much walking is done to see even the smallest fraction of each amazing site.

They are the sources of incredible history, culture, legend, engineering and architectural ingenuity, skill and sheer manpower. From grand scale walls, buildings, lakes and gardens, all man-made, Beijing is one of my favorite cities, but it is also the ancient hutongs that capture me.
These are the traditional living quarters of the poor majority, usually housing several families in one hutong, and living in what we Westerners consider primitive condtions. Parts are being demolished while others refurbished into trendy cafes, boutiques and hostels, and to get lost in the maze on a rented bicycle would be one of my aims the next time I visit Beijing.
