These days parents in China face a new challenge trying to protect their kids from porn, but not just on then internet, on mobile phones too.
More than 50-million primary and high school students cell phones and almost all have SIM cards that can access the internet. It's a combination that makes it extremely difficult to censor children's acess to harmful media. Ren Ting takes a look at the efforts being made.
One can buy a SIM card in newspaper booths like this one. There are hundreds in a city like Beijing.
This salesman says all the SIM cards have access to the Internet. No application or registration is needed.
The function itself does no harm, but hundreds of porn websites make it a great threat to millions of teenage cell phone users.
Lawyer Tang Hongxin said, "In law, they are individuals with no civil capacity or having limited civil capacity. They can be easily tempted and indulge in harmful messages like porn, violence and evil religions. The outcome could be unexpected and in a bad way, if we have no restrictions on Internet services to minors with cell phone."
Legal experts advise government regulators to learn from Japan, which has the same problem.
Lawyer Tang Hongxin said, "Japan has recently issued a regulation on this issue. Internet services to minors cell phones are cut off between ten p.m. and six a.m the next day. And access to harmful websites will be stopped within a 24-hour supervision system."
