Cast & Character List
Chen Shanchong as Guo Bofei
Meet Guo Bofei, the kind of cop you want on your side when things go sideways. As the Chief Inspector of the Serious Crimes Unit, he's not just calling the shots—he's out there in the thick of it. Bofei is the definition of loyal and fearless, someone who carries the weight of responsibility like it's second nature. He doesn’t just talk about doing the right thing—he does it, every single time.
What makes Bofei even more compelling? He’s got history. Alongside his fellow officers Jiang Xiwen and Liu Li, he trained under the legendary Sergeant Luo Youbang. That bond runs deep, shaping the way Bofei leads with both heart and grit.
In Anonymous Signal, he’s not just chasing criminals—he’s confronting the ghosts of the past, navigating loyalty, justice, and the high-stakes world of serious crime. Chen Shanchong brings a grounded intensity to the role, making Guo Bofei one of the most memorable characters in the series.
Moon Lau as Jiang Xiwen
Meet Jiang Xiwen, the sharp and unshakable Chief Inspector of the Criminal Intelligence Unit. If there’s chaos, she’s the calm in the storm. Known for her cool head and razor-sharp instincts, Jiang isn't just a cop — she’s the kind of leader who commands respect without raising her voice.
Back in the day, she was tight with fellow officers Guo Bofei, Liu Li, and Sergeant Luo Youbang. They weren’t just colleagues — they were a team, bonded by countless missions and late-night stakeouts. But everything changed three years ago.
During a high-stakes operation, tragedy struck: Luo was killed in action, Liu ended up in a coma, and Jiang walked away with more than just physical scars. She blames Guo for what happened that day — and that blame turned into a rift that tore their once-solid team apart.
Now, Jiang Xiwen is on her own path. She’s still the best at what she does, but the past hangs over her like a storm cloud. And in Anonymous Signal, where every clue counts and trust is a rare currency, Jiang's story is far from over.
Owen Cheung as Zhao Junlang
In Anonymous Signal, Zhao Junlang is the kind of guy who walks a tightrope — undercover, deep inside a criminal organization, and constantly one wrong move away from blowing his cover. He works for the Intelligence Unit, but don’t expect a desk job. He’s knee-deep in danger, gathering intel from the inside while trying to stay alive and ahead of suspicion.
Junlang’s mission forces him to team up with two people who—let’s just say—don’t exactly get along: Jiang Xiwen and Guo Bofei. There’s history between those two, and it’s not the friendly kind. But when you're chasing down leads in a high-stakes investigation, personal grudges take a backseat. Like it or not, this unlikely trio has to work together to crack the case.
Zhao Junlang brings the calm under pressure, the grit, and the street smarts to make it all work — or fall apart. Watching him navigate danger from all sides is half the thrill of the show.
Tiffany Lau as Wen Jiali
Don’t let her fresh-faced look fool you—Wen Jiali is not someone you want to mess with. As a rookie inspector, she’s already made waves for being fiercely independent, incredibly tough, and laser-focused on the job. She’s the kind of cop who doesn’t just talk the talk—she can seriously throw down if things get messy. Her combat skills? Let’s just say she could probably take down a perp with one hand tied behind her back.
Her grit caught the eye of none other than Chief Inspector Guo Bofei from the major crimes unit, who handpicked her for a high-stakes undercover mission. Her assignment? Infiltrate a nightclub and get close to a twisted serial killer who’s been terrorizing the city. It’s the kind of job that would rattle most seasoned officers, but Jiali steps into the darkness with nerves of steel.
She’s walking a tightrope between danger and discovery—one wrong move, and she’s blown. But if anyone can pull it off, it’s Wen Jiali.
