1. ICBC has stopped processing related cards and passbooks. What you did before can still be used as usual.

2. Cards are of course better than bankbooks. Passbooks are not suitable for carrying around. If you must have both, start them separately. Open online banking at the card window, and then link the passbook to register an online banking account. You can achieve independent association online. You can transfer money to each other, etc., all for free.
