It's a documentary by the China TV channel that produces Day Day Up.

Narration: ... released albums sweep the music charts being champions. They "attack" the Asian markets, hold world tours,take part in idol dramas. They are having a very prosperous career in the entertainment industry. Compared to their trainee days, their lives have made a 180 degree turn.
