The fourth mission, Concept Evaluation, is revealed. Trainees are presented with 5 new original songs of varying genres. They are placed into groups of 12 via fan votes. Temporary Center positions are picked as only 7 trainees may perform each song following eliminations. The second elimination takes place with only the Top 35 contestants to remain.
The third mission, Position Evaluations, begins. There are 5 songs for the vocal category, 4 songs for the dance category, and 4 songs for the rap category. The trainees with higher rankings pick their songs first, and once the chosen song reaches its member limit, the later trainees can no longer pick that song.
The first elimination takes place with only the Top 60 contestants to remain. Polls are held amongst the trainees for "Best Visual" and "The Person I Would Most Want to Introduce to My Little Sister". The trainees play a game to obtain Chinese New Year presents for their fans. The mentors also hold a dance battle, where the trainees dance to "Ei Ei" at various speeds, to help the trainees relax. The winner of the dance battle requests for a group Hot Pot outing as his wish, to which the director agrees.
