Her 1st big scandal was in 2015, when netizens thought that she had bought the popularity vote on sixteen, because she wasn’t in the top 7 at all during the first 5 episodes. They said she only got in because she was pretty. This scandal went away soon after Twice’s debut stage.
Her 2nd big scandal was during Dance the Night Away Era, when she had red hair and was compared to Rosé from Blackpink, and people even accused Hua of stealing her look. This dies down when people realized that Ddu-Du Ddu-Du came out after Dance the Night Away.
After Stray Kids had debuted, Hua was photographed looking at Chan with a bored expression as he was talking. Netizens thought she was being rude to him and didn’t care about what he was saying. Onces were saying that she was probably just tired. Hua eventually cleared this up on a live, saying that Chan was saying he had the “mental capacity” of a 5 year old, and Hua didn’t understand what he said.
She had her 1st dating scandal in 2019, when she was photographed with Mark from NCT at a coffee shop. This was quickly shut down by both companies, stating that the two idols were working on a song together.
Another scandal was during Twicelights, when a video of her crying over Mina not being on tour went viral. People accused her of trying to get attention, but Onces stood up for her, talking about how close they were.
During More and More Promotions, Hua was talking about how when they go to the airport and get mobbed, she normally has panic attacks. People thought she was trying to get more attention, and then her words got flipped and people thought she was being ungrateful towards the fans.
