As far as I know, Huaxia Bank's credit cards are mainly applied through the branch counters or credit card account managers. You can check the contact information of the local Huaxia Bank office in official website, contact the account manager to handle it at home, or go to the branch yourself. Because you want to apply for the owner's credit card of Huaxia Bank, you need to provide your own car driving license.
Huaxia Bank official website has a fast online credit card processing channel, but the online application process is not clear, so you can also fill in the application materials online now, wait for the bank's reply or take the initiative to contact Huaxia Bank customer service to inquire about the follow-up matters of online application.
