This is definitely not groundless. Let's take a look at Han Geng, who once worked as an intern in Korea. Han Geng can be said to be an earlier batch. He is a domestic artist who has worked as an intern in Korea. He said in social media and interviews with some variety shows that Korean brokerage companies not only train their body dance songs, but also train them how to answer when they meet reporters, when to do what kind of actions, when to have what kind of expressions and when to show surprises.
In addition to Han Geng, there is also a top popular artist Adam, and his experience can also explain all this. Adam once said in an interview that he had experienced very hard training before his debut, and there would be professional instructors to guide you on what to say and do on any occasion, and even deliberately cultivate a little posture of yourself, such as poking your head with your fingers, or facing each other. These are all trained.
Have you seen our little sheep, Ley? LAY's performance, whether on the stage or on the judges' bench, in variety shows or even in private, makes people feel particularly polite. Of course, these are related to personal qualities, but more importantly, LAY has also received training from Korean trainees. This kind of training makes LAY look so polite, temperament and culture now. Training before her debut is inevitable.
