Fei revealed a funny episode she had while she was learning Korean!

She was a guest on KBS 2TV's 'Happy Together 3' where she revealed, "I wasn't popular when I was growing up. People have a dark complexion from the area I'm from, but people with more lighter complexions were the ones who were popular."

She also shared a funny story she had after she moved from China to Korea and began learning Korean. She said, "I kept saying, '?? (Ah, sh*t)'. I didn't know it was a curse. I thought it was just a regular exclamation phrase."

It's a good thing someone told her what it actually was, or she could have had an embarrassing experience on TV!
