Will the chats between two related QQ accounts be cross-linked?

Hello, I am happy to answer your question:

The relationship number is not related to the space.

The spaces are independent of each other. Say, diary, etc. are not relevant. Only unread QQ messages will be reminded.

I hope my answer will be helpful to you. If you still have questions, please click to ask. If you are satisfied, you can choose to accept the answer. Thank you!
