I have a 24hr layover in Beijing. I'm interested in the wall, forbidden city, and night life.

If you arrive in BJ early in the morning, it is suggested you charter a taxi to go directly to Mutianyu Section. When you get back to downtown, you may pay a visit to Jingshan Park. From the top of the hill inside the park, you may have a full view of the Forbidden City.

If you land at around noon, you may go to the Wall immediately, and visit the Forbidden City on the second day's morning.

As for the night life, you may either choose a teahouse in Tianqiao Area to enjoy the BJ opera, or take a sip in a bar at Sanlitun Bar Street. Both are great to kill the night.
