In April 1997, Bai Bingbing's daughter, Bai Xiaoyan, was kidnapped on her way to school. After over ten days without rescue, she was ultimately killed and her body was discarded in the Zhonggang River, shocking society. The police launched "Operation 0414" to hunt down three suspects, Chen Jinxing, Gao Tianmin, and Lin Chunsheng, but a series of violent incidents followed, including shootouts and hostage situations, resulting in four deaths.

During the investigation, Bai Bingbing emotionally appealed for her daughter's safe return at a press conference, only to later receive the tragic news of her daughter's murder. Forensic examinations revealed that Bai Xiaoyan had been severely abused before her death. Public sentiment surged regarding the case, prompting the National Police Agency to form a special task force.

Despite facing multiple gunfights, the police overcame significant challenges and ultimately located the suspects, leading to many casualties and societal outrage. After a tense 21-hour negotiation, the remaining suspect surrendered, but the aftermath revealed more horrors, with one suspect dead by police fire and another committing suicide. This tragic series of events left a deep scar on Taiwan's public safety history.
