If you think having one pair of identical twins in the same class is confusing enough, imagine having six. That's what happened in a nursery school in Yilan this semester, where the teachers are having a hard time keeping track of who's who.

Even with this pair of identical twins

How do we tell them apart?

The elder sister points to her younger sister's mole to show the difference between the two.

Their teachers who often get mixed up must rely on the mole to tell them apart.

This is enough cause for headache for the teachers already, but the confusion escalates as this nursery takes care of not one, not two, but six sets of identical twins.

Confusing one twin for another often results in unwanted consequence.

Oftentimes the kids need to take their medicine, and the teachers must repeatedly make sure that they don't give medicine to the wrong twin.

This actually isn't the first time that the nursery has had to deal with so many sets of twins.

Four years ago, they had to take care of eight sets of twins.

Although the twins are adorable, the teachers swear to separate the twins into different classes in the future to avoid confusion and headache.
