Hello, I'm glad to answer your question. Identity conversion needs to be associated with an education cloud. 1. Associate the child's account, and click the "Associate" button on the home page to enter the association interface. 2. You can also make association in the Personal Center-Associate Children interface, enter the child's account number, select the relationship with the child, and click "Confirm Association" after selection, prompting "Association succeeded, waiting for the approval of the other party". 3. Log in to your child's account and click on the Personal Center in the upper right corner. 4. Select "Associated Parent" and click "Confirm Association".
