No way, kid! It is wrong to use someone else's ID card to participate in online games, and it is also illegal. Every gaming platform will require players to provide true identity information to ensure the fairness and security of the game. If you use your sister's ID card, it will not only cause her trouble, but may also put you at legal risk. In addition, many online games have age restrictions. This is to protect primary school students like you from being exposed to content that is not suitable for you. You can choose some games that are suitable for your age, or discuss with your parents to see if they agree with you to play some fun and healthy games. If you really want to play games, it is recommended that you communicate with your family to see if they are willing to help you register for an account that suits your age. This will not only allow you to play the game legally, but also reassure your family and know what you are playing. Remember, honesty and compliance with rules are very important qualities. Doing so can not only protect yourself, but also win the trust and respect of others. Come on!
