I am, however, fortunate that I have such great students. Students in America ‘go’ to school whereas students in China essentially ‘live’ school. They begin their school day when they wake at 6AM and the last class of the day finishes at 10PM. Two hours are given for lunch but they must remain in their dorms for the last 70 or so minutes, presumably to sleep.
