It seems that while filming for the show, one of the female contestants fell and suffered an injury, but none of the girls attempted to help their fellow contestant. You can see at the beginning of the clip above that the girls are also having a hard time focussing on filming, chattering away despite the fact that one of the girls was injured.�

Seeing this, Tao began yelling at the girls to stop talking while numerous staff members are hard at work filming. After storming off in anger, he returned a little calmer and began recollecting his own trainee days. He shared, "When I was a trainee I couldn't eat whenever I wanted to. 20 of us lived in one apartment, but I never complained once. When I debuted, I never argued with my group members over scenes. I was never envious of members who were more popular�because when you have those group members, other members will also have a chance to be discovered."

Lastly, Tao stressed to the contestants that the most important thing to learn before debuting was to become a good person. Watch the emotional clip above.�
