How difficult is the training process for Korean trainees?

It is very hard. Just being selected to be a trainee in South Korea is already a very hard process. It is hard-won for trainees to get the opportunity to go to South Korea, so the competition between them will become even more intense. Most companies have an elimination system that allows trainees to form teams for training. The training content mainly includes: "vocal music, dance, body shape, foreign language, etc." Of course, physical training is essential. Even girls have to lift iron every day. Of course, the hardest part is not the body, but the mental state of being oppressed for a long time. Because it is an elimination system, this means that if you don’t train hard and catch up, sooner or later the opportunity will leave you. The most fearful thing as a trainee is not being seen by others. If you practice well, you can debut. If you don't practice well, you will practice forever. And in the past two years, due to the rise of the idol market, many young people believe that this is a path that can bring them flowers and applause, making the industry more and more competitive. Just like thousands of troops crossing a single-plank bridge. The trainees who make it out must have experienced tremendous hardship and endured tremendous psychological pressure.
