Chinese students are often busy with study, especial before they go
to college. Being primary school student, every child is expected to
go to college and usually seen loading with a heavy schoolbag.
Go to middle school means more exercises and exams. They spend
little time on fun. It is too much for them. But, they have to face
with the challenge of the college entrance examination. But once
becoming university students, some students are addicted to playing that
they can’t graduate. Measures must be done so that students can
enjoy their life while learning in primary or middle schools. At college,
students should learn enough to make a living before graduation.
