BEIJING, Aug. 23 (Xinhua) -- A national training session for teachers on children's online safety concluded Thursday in Shenzhen, south China's Guangdong Province.

The session, jointly hosted by the National Office Against Pornographic and Illegal Publications and Chinese Internet giant Tencent, was aimed at enhancing teacher's knowledge on how to teach children about online safety.

A total of 62 teachers from primary and junior high schools in 31 provincial-level regions took part in the training session. They will take the information they have learned back to schools across the country.

During the session, online safety specialists with Tencent and legal experts from the office gave the teachers lectures on various topics including laws and regulations concerning cyberspace conduct, online habits of teenagers, and how to design online safety lessons.

In 2017, the office and Tencent agreed to jointly develop online safety lessons for Chinese children. Teachers were sent to 25 primary and junior high schools in more than 20 provincial-level regions to deliver classes to over 150,000 students.

A survey conducted earlier this year by the Central Committee of the Communist Youth League of China, Chinese Academy of Social Sciences, and Tencent warned that pornography, internet fraud and cyberbullying had become major online threats for Chinese children.
