China bans students from wearing bra ahead of examinations

More than nine million students packed exam halls across China for the opening day of the country's university entrance exam on Friday - with attempts to stop cheating even leading to bans on metal bra clasps

Students in the northeastern province of Jilin were banned from wearing clothing with metal parts and education authorities installed metal detectors in exam centres to clamp down on "wireless cheating devices"

Authorities have become increasingly concerned about the risk of examinees using devices such as smartphones -- some of which have become smaller and easier to hide -- as an illicit aid during tests
