After qq deletes friends, will the likes from friends in the previous space be displayed and kept?

Will keep it. However, since you have deleted the other person, his nickname will also change, but the record of praise still exists.

How to set space access rights?

In addition to setting access rights for spaces, logs and photo albums also support setting access rights.

Please log in to QQ space first, and click Space Quick Setup in the toolbar above the space-> Permission setting-> Access rights-> Select the permission category to set.

Note: If other people are not within your space access rights, they will be prompted to set access rights when they visit your space. You can modify the permissions and let the other party visit again.
