1. Wait a while before applying: If the application fails, you can wait a while (usually 1 to 3 months) before applying, which will improve the success rate of the application.

2. Change the bank card: If the bank card is unable to lend money due to abnormal status, you can change the bank card and apply again the next day.

3. Enhance personal credit: If the credit record is bad, you can improve the application success rate by enhancing personal credit.

4. Understand the reasons for the audit failure: You can contact Wanka customer service to understand the specific reasons for the audit failure, so as to make targeted improvements.
