Why is the credit card pre-approval limit in China Construction Bank mobile banking?

A display such as "Pre-approval, application form to be submitted, congratulations, the card you applied for has been approved, please check it" indicates that the card has been approved, "I need to confirm it myself, and I need to confirm it within 7 days" indicates that the information is insufficient (personal information, financial proof or no signature), and additional information is needed.

This short message will generally be sent once or twice (if the customer fails to handle it after the first reminder, a second reminder will be sent), and it will be valid within one month after receiving the first short message.
