Harmony Primary school is situated in picturesque Hangzhou, but with 740 students and teachers, only 1 male toilet of 6 seats and 1 female toilet of 8 seats, crowds are guaranteed at every class changeover period of 10 minutes. So students try to not drink water to avoid going to the toilet, some wet themselves because it is too crowded to get to the toilet in time.
