QQ Group Classroom is an online education platform launched by Tencent, which can be used for online live broadcast and interactive learning. In QQ group class, whether to open the wheat automatically depends on the rules set by the group owner or administrator.

According to the information I have learned, QQ group provides a variety of setting options, including whether to turn on the microphone automatically. Group owners or administrators can make corresponding settings according to actual needs, and decide whether to allow students to open wheat freely or need permission to open wheat.

Therefore, whether to automatically open the wheat needs to check the specific settings and regulations of QQ group classrooms. You can contact the administrator or owner of this group to learn more about its settings and regulations.
