Chinese authorities launched a nationwide campaign on Sunday to present 1 million DVD disks on security education to school children in major cities.

Sponsored by the China National Committee for the Wellbeing of the Youth (CNCWY), the Central Committee of the Communist Youth League and the All-China Women's Federation, the DVD disks contain educational programs that teach young people how to protect themselves and better adapt to society.

The authorities will also conduct school security lectures and sample surveys of school children's parents regarding security concerns in Beijing, Nanjing, Changchun, Shijiangzhuang, Nanchang, Nanning, Ningbo and other major Chinese cities.

Li Qimin, deputy secretary-general of the CNCWY, said that school security is a responsibility for all social circles. One of the major reasons for school tragedies is the children's inadequate knowledge of self-protection and know how.

From March through May, a series of brutal school stabbings occurred in Jiangsu, Shandong, Guangdong and Shanxi Provinces, which caused dozens of deaths and injuries.
