How did my husband bind my rookie station?

1. Open the rookie station APP on the mobile phone desktop, click the button I in the lower right corner, and click the button Settings in the lower left corner.

2. Click the button to bind my mobile phone number management with relatives and friends, click the Open button to add more commonly used mobile phone numbers, enter the mobile phone number, and then verify the SMS, and bind your own rookie station on my husband's mobile phone.
