Almost every group has performed. . . Baidu search "combination (artist) name+cuteness" ensures that you can find any combination you want to see! Some groups don't perform on the show, but take selfies, behind-the-scenes tidbits, meet fans and so on.

I have seen: CNBLUE (radio program) boyfriend (autograph session) SUZY (idol of the week) Li Dongxu (strong heart) sistar, AOA (backstage), Apink? SJ (silver moon TV, or Sina interview, I forgot = = There are other programs! ) In short, there are many more. . . . . . .
