Well, this is the information from the insider. Gosh, I don't know anymore.
I'm afraid if they purposely set this show to the failure by how terrible they handling it, to make people begging for the produce series to comeback.
-They didn't mentor them. (The planet masters only come for the interim check compare to produce series)
-They didn't provide translator. (They said the translator will be available for 24/7 but according to Liang Qiao, they are not)
-No agency to hold the activities of the groups while they are less then a month to the finale.
-Focusing on evil editing, not the growth of the trainees.
-They treat Chinese group badly, and overwork the girls.
-They force the girls to change their style even they don't like it. Ex, wang yale.
-Strict diet. (Liang Jiao didn't eat for three days during connect mission in order to loss weight)
-The contract probably only a year because mnet want to revive Produce series next year probably after the Iland series. They will starting it with the girls as usual I think to attract viewers.
-Etc... There's more maybe that I forget. But special thanks to C-trainees that very open about this thing.
