Beijing China is a major metropolitan city with a mixture of old and new architecture, a lot like New York, except the "old" in Beijing is really, really old. I was on vacation in Beijing for only 3 days. The most famous tourist site is, of course, the Forbidden City (Imperial Palace). I would also recommend you try to get to the Temple of Heaven, which is also in the city.

If you have a day available, it is not a long bus tour to go to the Great Wall of China. The tour was lead in English and it also stopped at Ming's Tomb and Sacred Way.
