we have a 14 hour lay over in bejing and want to make a very mini trip of it. we have according to our flight schedule (not sure if these are bejing times.. hope not) from 2am til 350pm. so lets say, be back at the intl airport by 2pm. what can we do in that short period of time??? we would love to see either the wall or the square if possible, but if anyone has any reccomendations,,, thx :)
