The 28-year-old finished top of the podium in the men’s Taijiquan-Taijijian combined event with a total score of 19.526.
Japan’s Tomohiro Araya placed second, while Tay Yu Xuan from Singapore took the bronze.
Yeung last competed at the World Games 2022 in the United States, when he brought home a bronze medal in the same event.
Wong Po-kee, the delegation’s chef de mission and honorary deputy secretary general of the Sports Federation and Olympic Committee of Hong Kong, China, said Yeung delivered a strong and determined performance in this year’s World Games.
“Whether wielding the sword or executing bare-handed forms, he demonstrated ease and confidence, delivering his moves with a harmonious blend of softness and strength, powered by profound internal energy,” Wong said.
“Through his consistent and outstanding performance, he got high scores in both rounds and successfully clinched the gold medal, promoting the national essence.
“His achievement is truly commendable and worthy of celebration.”
Yeung’s achievement came after Grace Lau claimed gold in women’s karate on Friday night.
