It may be because Bank of Communications does not accept users who have cancelled their applications to reapply. If the landlord's application is rejected now, he can wait for another user to apply after three months. In addition, the landlord should try not to cancel his credit card after cancellation, because it is more troublesome to reapply after cancellation. In addition, the landlord needs to prepare his own economic documents for application after three months. The more complete the better, the above is the information I have learned. I hope my answer can help the landlord!
