Your other CCB cards can be used for normal transactions, and this will not affect your credit card application.
The basic conditions for applying for a CCB credit card are: be between 18 and 70 years old and have full capacity for civil conduct; have a stable career and income, be able to repay principal and interest on time, and have good credit. The bank mainly focuses on your work income, credit record, repayment ability, assets, etc. The transaction records on your other CCB cards will not have any impact on card application.
