Tencent released videos to all group performances from team competition in Produce Camp 2020.

Multiple groups were competing under two "main" teams, which made it not only battle between trainees but also a battle between mentors.

Team LTG - team formed by Luhan and Tao
Bu Song - team formed by Mao and Victoria Song

That's really touching and sad story. Those five girls were on the list of trainees that should participate in the very first round with 1-minute performances.
Wuhan went on lockdown and they couldn't leave the city to join Produce Camp. Now they were allowed to have their small performance on-stage. Sadly they couldn't stay and join other trainees because it will be against show rules.
