If you’ve spent any time on TikTok or Reddit lately, you’ve probably seen a familiar face doing some absolutely insane wushu flips. He looks older, leaner, and—honestly—kind of like he hasn't aged a day since 2010. That’s Zac Wang. Or, if you’re a purist, Zhenwei Wang. Most people just know him as Cheng, the kid who spent an entire movie making Jaden Smith’s life a living nightmare in the Karate Kid remake.
The internet is currently having a collective meltdown because Zac Wang is back in the spotlight. With the release of Karate Kid: Legends in 2025, everyone is asking the same thing: Is Cheng coming back to the Miyagi-verse? Learn more on a similar subject: this related article.
What Really Happened to Zac Wang After 2010?
After the 2010 film became a massive hit, Zac sort of vanished from the Hollywood radar. You'd think a kid with those moves would be in every action flick, but he took a different path. He didn’t just hang up the uniform. He actually leaned harder into the craft.
Zac Wang joined the elite Jackie Chan Stunt Team. That is not a small feat. We’re talking about the 8th generation of the most legendary stunt crew in cinema history. He’s been working behind the scenes for years, sharpening his skills in nunchaku, spear, and sword. If you saw the Marvel movie Shang-Chi and the Legend of the Ten Rings, you actually saw his handiwork. He was right there in the mix as a stunt performer. More reporting by Variety highlights similar perspectives on the subject.
He's 29 now. It's wild to see him standing next to Jackie Chan today, looking basically like a younger, taller version of the master himself.
The Confusion Between Zac Wang and Ben Wang
Okay, let’s clear this up because it’s confusing everyone. There are two "Wangs" in the Karate Kid universe now.
- Zac Wang (Zhenwei Wang): The OG bully Cheng from the 2010 movie.
- Ben Wang: The new lead in the 2025 film, Karate Kid: Legends.
Ben Wang is a phenomenal actor from American Born Chinese. He beat out 10,000 other actors to play Li Fong, the new protégé mentored by both Jackie Chan (Mr. Han) and Ralph Macchio (Daniel LaRusso). People see the last name "Wang" and the Karate Kid title and immediately think Cheng is the new main character.
He isn't. But—and this is a big "but"—Zac has been seen all over the Karate Kid: Legends promo trail.
Why Zac is Hanging Out on the Legends Set
Zac has been spotted supporting Jackie Chan during the Karate Kid: Legends press runs. He even posted a video of himself and Jackie that went viral. Fans are convinced it’s a "soft launch" for a cameo.
Think about it. Legends is a massive crossover. It brings together the 1984 world and the 2010 world for the first time. Having Cheng show up as an adult—maybe even a reformed martial artist or a rival coach—would be the ultimate fanservice. Even if he’s "only" there as part of the stunt team, his presence on set has kept the rumor mill spinning at 100mph.
Zac Wang’s Martial Arts Evolution
The kid wasn't just "acting" like he knew kung fu. He was a wushu prodigy before the cameras even started rolling. He started training at the Beijing Shichahai Sports School when he was barely a sprout.
- Styles: He's proficient in traditional Wushu, Karate, and Taekwondo.
- Weaponry: He is a beast with the staff and nunchucks.
- Professionalism: Being on Jackie Chan’s team means he isn't just a "movie fighter." He’s a tactical athlete.
Honestly, his social media is a goldmine for martial arts geeks. While Jaden Smith moved into music and fashion, Zac stayed in the dojo. He’s often seen training in Dubai or Beijing, pulling off gravity-defying kicks that make his 2010 tournament performance look like a warm-up.
Will We See Cheng in Karate Kid: Legends?
Sony is keeping their cards close to the chest. We know the story follows Li Fong (Ben Wang) moving to New York and getting bullied by a local karate champ named Conor Day (played by Aramis Knight).
But here is the theory: Mr. Han (Jackie Chan) has a history. If he’s in New York training a new kid, what happened to his old students in Beijing? Redemption is the biggest theme in this franchise. Just look at Johnny Lawrence in Cobra Kai. Bringing Zac Wang back as an adult Cheng would fit the "Miyagi-verse" DNA perfectly.
Even if it's just a 30-second cameo during a tournament scene, the hype is real. Fans on Reddit have been vocal about wanting to see a "Cheng vs. Daniel LaRusso" interaction. Can you imagine the clash of styles?
The Staying Power of Zac Wang
The reason Zac Wang is trending in 2026 isn't just nostalgia. It’s the fact that he actually put in the work. He didn't ride the "child star" wave into reality TV. He went back to the roots of martial arts cinema.
He represents a bridge between the old-school Hong Kong action style and modern Hollywood. Whether he’s in front of the camera as Cheng or behind it as a stunt coordinator, he’s become an essential part of the Karate Kid legacy.
If you want to keep up with what he's doing, your best bet is following his stunt team updates. He’s frequently popping up in high-end action choreography videos that put most CGI fights to shame.
Actionable Insights for Fans:
- Watch the Credits: When you see Karate Kid: Legends, don't just leave when the lights go up. Look for "Zhenwei Wang" in the stunt department or "special thanks" section.
- Follow the Stunt Team: To see his best work, look for the Jackie Chan Stunt Team (JCST) official socials. That’s where the real training footage lives.
- Distinguish the Leads: Remember, Ben Wang is the 2025 star, but Zac Wang is the legacy bridge. Both are incredible martial artists, but they represent two different eras of the franchise.
The "Karate Kid" world is bigger than ever, and whether he’s a villain or a hero, Zac Wang has definitely earned his place in it.
