In fact, this should also start with the development of Korean entertainment industry. There is a well-known entertainment company called sm Company in Korean entertainment circle, which selects 100 trainees from all over the world as its own students every year. Few people can be drawn from this 100 exercise, and they also have high requirements for the selection of these students. They must ask these students to work very hard, whether it is face value or personal talent.
Moreover, in the way of training these students, many means are also used, and the requirements are particularly demanding. For a simple example, if an intern can't better show his talents in front of fans, then more and more people will think that this intern is not particularly excellent and will be eliminated by this society. Therefore, South Korea's requirements for trainees are particularly high.
This allows each of them to appear in front of fans as they wish, and also carries a lot of traffic. Moreover, the stars of this series will also be crowned with some people when they debut, and the impact these people bring to these trainees is also particularly great. Many trainees will show off their personal designs in this society, which is why so many fans like this star, but I personally think that a star should have his own acting skills to be better.
