According to the arrangement of the Festival Group, if there were trainees from Class A among the 15 teams, the trainee from Class A would be the leader. If there were no trainees from Class A, the group would choose a leader after the grouping was over.
The team leader was mainly in charge of mission arrangements and other work, but he was not the team's center. The members themselves chose the center of the team.
"Now we're entering the mutual selection stage. The trainees will take the initiative to sign up for the team they want to go according to the class order, A, B, C, and D. If the captain agrees, the team formation will be successful. If the team leader disagrees, the trainee can only be selected by the team leader who has insufficient people after the class allocation."
The rules were not complicated, but it was a little cruel for the trainees of Classes C and D. They would again face the awkward situation of being chosen.
