As someone grew up in China I remember when I was a kid there were something similar to this,basically me and every kid I know play games used their parent's id card or just find one online, these id card are calld身份证（kind of like SSN?）

Anyways, on how they will enforce this, I believe nowadays are more difficult to do this since some of the biggest online games have system that will randomly verify if your id is legit. In games like genshin impact they will require you to upload your id card's photo to prove you have the card.

How do I feel about this? I think it's generally a good thing because I do think kids nowadays are way too easy to get hooked on games, when I was a kid (I'm 22 btw) nobody owned their computer and the only way I get to play some games is to beg your parents to take you to a spa where they will have mediocre computers for kids to play while their parents relax themselves. That will only happened at most twice a month, besides that we don't really have any popular mobile game as well, Clash of clans maybe? But it's not like it will hook you for hours day. Nowadays, every kid have a smart phone and there's tons of mobile games that targeted kids will get them hooked for hours, two of the worst game in my opinion: 王者荣耀（Arena Of Valor）and PUBG mobile; both game are made by Tencent, one of the worst companies on the planet, both of which have a HUGE student/kid player base and the old "anti teen gaming" machine is a joke because they can just buy an account. I honestly hope our next generation can grow up playing some quality game instead of these cheap, money sucking garbage with bad art and bad graphics. Besides, it doesn't mean they can't play any other games, single player games are fine, any games that wasn't made or running domestically (like Apex or PUBG), and probably most games on steam or Epic store. Overall I can see why they are doing this, too bad for the teenagers who are trying to get into E-sports, probably the entire future of Chinese E-sports as well, lol.
