Learning alone without friends is solitary and ignorant; If a person only studies alone without making friends or discussing, it is highly likely that their progress will be very slow and their perspective will be singular.

The purpose of organizing this team activity is to encourage everyone to share their knowledge by standing on the podium and throwing out the questions.
