FIESTAR has reunited as a full group after seven years, and it's been revealed that member Cao Lu played a key role in their reunion. 

While pursuing solo activities, Cao Lu saved money through live commerce to personally purchase the copyright for their song "You're Pitiful." However, she also disclosed that she is currently on a travel visa instead of a work visa, which prevents her from engaging in profit-making activities, meaning she has been participating in broadcasts without being paid.

On September 27, the YouTube channel 'No Back Tak Jae Hoon' featured a video titled "Cao Lu & Yezi: The Great Effort to Revive FIESTAR After Struggling in China." In the video, Cao Lu and Yezi appeared together for the first time in six years. 

Cao Lu commented, "It feels like I'm appearing on Korean TV for the first time in about four years." Host Tak Jae Hoon humorously asked, "Are you an illegal immigrant then?" to which Cao Lu explained her situation, stating, "I’m currently on a travel visa, so I can’t engage in profit-making activities. That’s why I’m doing these broadcasts for free," surprising everyone.

Fans were deeply moved by the story, with comments such as, "Cao Lu is amazing. Her love for the group is obvious," and "It’s incredibly touching that she’s coming all the way to Korea to reconnect with fans."

Previously, on the YouTube channel 'Recent Olympics,' Cao Lu mentioned that although she used her own money for FIESTAR’s activities and the copyright earnings would be fairly distributed among all the members.

Korean netizens were impressed with Cao Lu's efforts in bringing FIESTAR together and commented: 

"Truly amazing. While most Chinese idols leave Korea behind and pretend they don't care, Cao Lu is doing the opposite. She worked hard in China to earn money and came back to Korea to reunite her group... I really hope FIESTAR succeeds!! I want Cao Lu to see that what she did was the right thing and that she made the right choice!"

"Cao Lu, you really care about the group. I hope things go well for FIESTAR."

"Loyal Cao Lu."

"Cao Lu is awesome. A woman of loyalty."

"Cao Lu, I truly hope you succeed! I hope this gives FIESTAR another chance to shine, and I really miss Yezi’s rapping."

"When Cao Lu went to China and appeared on shows, people criticized her and left nasty comments. Where are those people now? I hope she continues to work hard and finds success!"

"There are people like her~ Truly incredible!!! What’s up with Yoo Seung Jun, who abandoned Korea and became an American?"

"Let’s hope FIESTAR truly succeeds!!"

"That's truly impressive."

"Cao Lu is really amazing. It's really not easy to make this possible."

"I can't believe she's using her personal funds to support FIESTAR. She's so amazing."
