Two university graduates are under investigation for selling equipment that could be used to help students cheat on exams.

Police in Nanchang, Jiangxi province, caught the duo earlier this month just before the graduate school entrance examination.

They were involved in the sales of special watches, eyeglasses, erasers, pens, wallets and vests that could be used to help them receive answers to test questions.

A radio receiver was installed in each of the objects and the cheater could obtain answers through an earphone and see them on a receiver.

The case remains under investigation. -China Daily/ANN
