If the minor has reached the age of eight, it depends on the specific amount. If the amount is within the reasonable range of its control, it is an effective civil legal act, and parents have no right to demand it back. If it exceeds a reasonable amount, parents can refuse approval and ask for a refund. For details, please communicate with the official customer service staff of the game party, provide some evidence to the customer service staff to prove that it is a minor recharge, and explicitly agree to file the account to recover the consumer props.
However, if a minor rewards some game anchors for a fee, these need to be communicated and handled by himself, and the game company will not take care of it.
