1. In fact, the so-called "random matching chat" service refers to the "limited time chat" function in QQ extension function. This service is still in the internal testing stage, and not everyone can use it!

2. Find the "QQ Extension" function from the top of the QQ contact list and enter to find the "limited time chat" service. Click on it to randomly match friends to chat together.

3. It should be noted that each user can only match 10 friends every day, and the time limit for each chat is only 3 minutes. Chatting friends can disclose their QQ numbers and add each other as friends!
