A girl who could have been in TWICE

I happened to watch a Chinese drama on TVING, and since the female lead was so pretty, I looked her up and found out she was a JYP trainee for 3 years.
Apparently, she left JYP and returned to China around 2015, before the audition program "SIXTEEN" that selected TWICE began.
(I heard she was close with Tzuyu; I wonder if she would have become a visual member of TWICE if she had stayed in Korea longer?)
