If the other party has no intention of continuing to chat/goes offline, "Your conversational partner has disconnected" will be displayed. It doesn't matter, you can try a few more chat partners, but the main thing is to improve the interestingness of your topics and your English expression skills. European and American people on chatfree mainly want to make friends or chat for pure entertainment. They also hope to make friends with the same language background. It is not very suitable for English speaking training. Therefore, try to have a "communication" mentality and talk more about international hot spots or domestic highlights.
