China’s government has made new rules limiting online gaming for children to three hours a week. The government says the move is meant to protect the health of children. It’s just one of many recent steps China has taken to limit the effects of the internet.

On Monday, China’s National Press and Publication Administration (NPPA), set out new rules limiting online gaming for people under the age of 18 in China. Under the rules, children can only play online games for one hour a night on Fridays, Saturdays, Sundays, or holidays. On these nights, gaming will only be allowed between 8 p.m. and 9 p.m..

The NPPA says the new rules are designed to protect the “physical [body] and mental [mind] health” of young people. The government is hoping to prevent young people from becoming “addicted” to gaming (developing a “need” to play games and being unable to stop). China’s government has said that gaming distracts kids from their families and school work.

Under the new rules, online gaming companies are responsible for making sure players use their real names and birth dates when they sign up. The NPPA says it will be checking up on gaming companies more often, to make sure they are following the new rules.
