Why are the members of Idol Trainee called "Dachang Boys" by netizens?

Idol Trainee is a very popular variety show with many stars. What's it like to be a big factory boy? Let's have a look. Many people don't understand why they are called Dachang Boys.

Idol trainees were recorded in Dachang Hui Autonomous County, Langfang City, so idol trainees are called Dachang Boys. Dachang is a place name and has no other meaning. Idol trainees suddenly won a lot of popularity. Of course, the nine trainees who successfully debuted are the most popular.

I think all the members who participated in Idol Trainee worked hard and were very active. Very popular. They are loved by many people through this stage. Popularity is also rising rapidly. This is a shortcut to fame, but before the launch of Idol Trainee, the public's evaluation of this program was not high. Because super girls and super boys used to be very popular, but gradually the public began to have aesthetic fatigue on these music talent shows.

Idol trainees have many unique conditions to succeed. For example, before China's music talent show, they all faced some amateurs and simply looked at singing skills. Idol trainees are faced with people who have a certain performance foundation, not only paying attention to their singing skills, but also paying attention to their dance strength.

One of my favorite members among idol trainees should be Kun. Because his rap skills can be said to be very good. Later, he became the basketball ambassador of NBA. Makes me like him more. This is why idol trainees are big factories, while boys are. What's going on here?
