You don't need your parents' signature, as long as the company (or the household registration management department where you want to move in) agrees to accept your account: first ask people if they want to accept it, then you can rely on relevant certificates (please consult the local account management window for details), and finally you have a new account book, and your parents' account book will give the words "account migration" on the card;
