Beijing will use new electronic equipment to prevent cheating on examinations for adults this weekend.
The new equipment, called "cell phone dog", can detect mobile phones receiving or sending messages.
The device is about the size of a pack of cigarettes.
It is estimated that over 100 people used cell phones to cheat during the examinations last year.
People caught cheating in the examinations automatically receive a score of zero.
