School of twins
Wuhan Optics Valley No. 15 Primary School has 15 pairs of twins, with two male-female fraternal twins, ten pairs of boys, and three pairs of girls.
Teachers were completely confused by the twins at first and then they consulted the parents who then took some measures to make distinguishing them easier. For the boys, they would pin a attention-catching badge on their clothes, and for the girls they would bind their hair in a different styles.
