What's the difference between visiting space and talking about space? If you don't visit the space, how can you just watch and not talk?

Talk about it, just look at the updated talk. In the visitor record, it will show that a friend has seen your conversation; Access to the space can be accessed through the space client to enter the space home page, read chat, read logs or photo albums. In the visitor record, it will show that friends have visited your homepage.

If you just want to have a look at the chat, you only need to look at the updated chat status of your friends, and you don't need to click on the friend space.
