I will be vigilant when using the equipment healthily. Will I be watched when I quit?

Still will. After creating a child account, you only need to enter "Settings", log in to the parents' "vivo account" and enter "Family Group" to switch quickly. Parents' mobile phone space and children's space can set face unlocking respectively. When the mobile phone recognizes the child's face, it will automatically enter the child's space, so there is no need to worry that the child will be disturbed by unrelated applications when using the mobile phone to study. The function can be opened in the homepage group of vivo account.
