Last full day in Beijing

Every morning after we get up and have breakfast, we stand outside of our hotel to meet the bus that takes us to another amazing landmark.  However, as we wait, we watch the opposite side of the busy street which is crammed full of busy shops...and Beijing high school students.  The students line up and yell, bend, run, jump, and hop to the order of their phy. ed instructor.  The number of students attending the school must be quite large because as one group rounds the next block to leave, another is ready to take their place.  Beijing doesn't have the space to create an outside gym for some high schools so they take to the streets (they are all quite slim).  At first this idea seems crazy but after to talking to Sabrina and our professor (both Chinese), it seems like quite a normal thing.
