BEIJING, June 6 (Xinhua) -- China on Monday published eight typical cases solved during a special campaign to crack down on piracy and online pornography to ensure the healthy development of young people.

The National Office Against Pornographic and Illegal Publications in February launched a campaign against production, sale and distribution of illegal publications and online content that could affect juveniles.

In one of the eight typical cases, police in east China's Zhejiang Province found 27 suspects, some of whom were minors, were using online chat groups to spread pornography for profit. The groups on chat service QQ had more than 600 members, the majority of whom were minors, according to the office's statement.

In another case, police uncovered suspects selling obscene videos via cloud storage services. The primary suspect in the case was a juvenile.

In other cases, police busted the illegal printing and sale of pirated books for children. Production and storage sites and illegal bookstores were closed.
