I wish I was being sarcastic, they actually do a 14+ hour day at my middle school. Here's the daily timetable Monday to Saturday. 5.30 rise. 6.00 running to martial music 6.30 breakfast. 7.30 lessons. 9.50 running to martial music. 10.30 lessons. 12.00 lunch and break. 14.40 lessons. 16.10 running to martial music. 16.30 sports, music, art and other extra curricular activities, 18.00 dinner. 19.00 homework and self-study in classrooms 21.30 finish. 22.30 lights out. Saturday school day finishes at 18.00. Sunday evening homework and self-study 19.00-21.30. They don't actually want people to THINK in mainland China, that could be dangerous.
