4-5 hours free in Beijing

[pdnb]

i will be in Beijing and have 4-5 hours free. Most of my co-workers go to Shenzen for buying rep purses or watches, but I will be only in Bejing and I thought i would ask. Is there some sight seeing that may be possible in this short amount of time?

Thanks,

Never been there, but the Olympic stuff would be neat to see and the Square and Palace.
