TNT Teens in Times (Video Collection)

This is a channel that occasionally uploads some of their videos. It may be previous or the latest and I will slowly organize it. (Organization can see in playlist)
They have a very long story until they debut and became celebrities. I hope I can compile a copy of their story.

Teens in Times (TNT) is a Chinese mainland male singing group launched by Time Fengjun Entertainment. It consists of seven people: Ma Jiaqi, Ding Chengxin, Song Yaxuan, Liu Yaowen, Zhang Zhenyuan, Yan Haoxiang, and He Junlin.
On August 25, 2019, the reality show "Typhoon Juvenile Transformation Battle" ended. Ma Jiaqi, Ding Chengxin, Song Yaxuan, Liu Yaowen, Zhang Zhenyuan, Yan Haoxiang, and He Junlin officially formed a group.
On October 11th, the group of seven members officially announced the name of the group "Teens in Times", abbreviated as "TNT", which means that the group will be full of firepower in the future and become unstoppable.
