  • After she played a musical role as "Patzzi" back in elementary school, she started working in the music industry. One of her supposed stage name was "PowG" which sounds similar to her musical role.[citation needed]
  • Her stage name, "Hwasa", means shining brightly in Korean. She chose this name because her birth name, Hyejin, is too common in Korea.[3]
  • An incident during the live broadcast of Music Bank gave her the nickname 화사자 (Hwa-Saja), or Hwa-lion. The reason is that her hair got stuck on her headband, and it raised her hair up, making it look like a lion's mane. It became a running gag between the members and the fans. Coincidentally, her zodiac sign is Leo, the lion.[citation needed]
  • It was revealed that she is sensitive when it comes to height.[citation needed]
