How to handle the secondary number for one card with multiple numbers?

Log in to China Mobile's mobile APP and click "Universal Card". Click to select "Choose a beautiful name". Select the attribution (same as the main number) in turn, fill in some easy-to-remember numbers, click Filter, and then click the number you like. Then click Order Now to confirm the submission.
