Teachers and parents have always spied on their children to make sure they were behaving properly. But in China the tables have turned as parents are making spy drones out their kids by planting surveillance devices on them to monitor their teachers.

New, easily available technological gadgets are making it easy for parents to turn their children into moles, and the smart watch appears to be their surveillance method of choice. These watches enable remotely controlled dialing or voice recording, and can be purchased from Chinese online retailers such as Taobao.com and Jd.com.

At one primary school in Shanghai, staff members were shocked to find that "more than a few" children in first and second grade were wearing surveillance devices, reports Wenhui Daily.

One parent of a child at the school admitted to eavesdropping on their kid's class using a smart watch. Using the smart watch to monitor the child's class, the parent sent information about what the teacher assigned to other parents before the children even got home from school.

Teachers and educators in China often refer to these types of parents as "monster parents," using a term borrowed from a popular TV show in Japan.

Carla Zhu of Shanghai bought a smart watch for her three-year-old who attends kindergarten from Taobao for about 400 yuan ($60), reports Global Times. ""If you send a command through an app installed on your phone, the watch will immediately respond and dial your number," Zhu explained.

Zhu said she decided to by the monitoring device because she was worried about her son being mistreated after seeing angry kindergarten teachers harshly scolding children at the entrance gate for being late.

"The teachers usually report positive things about my boy, but he sometimes tells me he feels unhappy at school," Zhu said. "He's too young to understand it all or express himself clearly, so I want to know what really happens to him at the kindergarten."
