How to batch process and group the information in Xiaomi's address book by computer?

Xiaomi Address Book does not support batch processing on the computer. It is recommended that you batch process the contacts in your mobile phone.

Contact person-> My group

Create a new group name: for example, all contacts.

Select all contacts.-> Plus then->; Select all groups and-> good

Wait ... All contacts will be added to all contact groups.

Now, delete all groups. Note: Deleting a group does not delete the actual contacts. This is the key. Now recreate all the groups you want. They have no members. Then use Xiaomi mobile assistant to regroup the contacts in the mobile phone in small batches! ! !
