Here, there's an unwritten rule about how to calculate an artist's debut year.
That is, after officially appearing in works related to the entertainment industry, it's considered an official debut.
Take Bae Juhyun for example, she's a member of Red Velvet, so her debut year is calculated as 2014.
But even before becoming a part of Red Velvet, she had already appeared as the lead actress in a senior's music video due to her beautiful appearance.
However, that wasn't considered her debut stage, nor was it an official appearance, and she wouldn't be performing for music shows, so the debut is still calculated from the debut stage.
Is Liu Xin'an considered an artist? If we talk about before participating in "Knowing Bros," he wasn't considered an artist.
But now... Liu Xin'an can actually be considered a bona fide artist!
In other words, Liu Xin'an's debut year is 2021!
For her? 2014!
A full seven years' senior.
