The card number and password of the new card are the same as those of the old card, and the landlord only needs to open it to use it.

Card opening method: use the mobile phone number reserved in CCB, edit the short message "CCJH# card number # last four digits of validity period", and then reply "QR#90" and send it to 95533. Of course, it can also be opened through his telephone self-service voice system, online banking, and bank counters (with ID cards and credit cards) at CCB outlets.

If the landlord has other questions, you can ask.
