After the end of the first year, the postal bank needs to issue an agreement to dissolve the group.
If you cancel the agreement, it's none of your business.
If the team hadn't been dissolved, he lent the money to Party B, and your two families didn't sign it.
Moreover, the loan officer did not go to your two households to re-investigate and take photos with you two households alone again.
That's none of your business. It does not meet the loan handling rules of the Postal Bank.
