Last summer holiday, some of you might have spent a lot of time playing video games online. However, you won’t be able to do this anymore. Recently, China introduced new rules that cut online gaming time for minors (未成年人), in order to prevent them becoming lost in video games.

Starting from September 1, 2021, minors will be allowed only an hour of play time between 8 pm and 9 pm on Fridays, weekends and public holidays. Services can’t be offered at any other time to them. The online game companies must also make sure that minors register (注册) or log-in (登录) with their real names.

However, this isn’t the first time that China has put limits (限制) on gaming time for minors. In 2019, it passed laws limiting play time to less than 1.5 hours on weekdays and 3 hours on weekends and holidays for minors, with no game playing allowed between 10 pm and 8 am.

The new rules quickly caused discussion. Some people support them, while others are surprised at how strict the rules are. “Children have little control over themselves, so they need guidance and monitoring (监管),” one user wrote on Sina Weibo. Others are worrying about it. “What if kids use their parents’ names to log-in?” asked another Weibo user.

The new rules also call on parents and schools to work together. In this way, we can make sure the rules are followed.
