"mz" generally means "like in seconds" in space comments.

The " " after "mz＋" is probably the commenter's intention to add me.

Every QQ user has a module called Talking in their own QQ space, which is the mood of the previous space. QQ chat can express your feelings. In "Tao Shuo" you can add some pictures, share exciting videos, and URLs. When typing, you can also try typing @ to talk directly to your friends. You can also forward interesting sentiments and spread happiness.

What you want to talk about can be something that happened around you, or something you have been thinking about recently, or it can be a classic sentence, or some music, a short video, etc. It is a very open communication platform, usually between QQ friends. It is a very important channel for friends to understand each other’s current situation. Many people post comments every day, and others can like and comment freely.

In addition, you can also follow other strangers, expand information sources, and interact with friends more abundantly every day.
