Yao Shen and his two "mentees" are sitting together in a little corner of the set, with two cameras trained on them. The flimsy partition surrounding them prevents Yao Shen from getting a good look at Xin Hulei on the other end of the set.
It's far to assume that he's enduring the same kind of questions, however.
He spares a wan smile at the two girls and tries to change subjects. "Ah, that doesn't matter right now, we should focus on devising a strategy to help you two make a good first impression."
Yao Shen was initially considering just saying whatever to get through the stupid show, but since they're apparently determined to expose him and Xin Hulei he needs to distract them somehow.
Song Wen clears her throat. "We can learn a lot if laoshi shares what worked for him."
Right, that's how it's going to be.
