To the excitement of an electrifying home crowd, China's young mixed doubles pair Feng Yanzhe and Huang Dongping got the host off to a scintillating start by beating the South Korean duo Seo Seung-jae and Chae Yu-jung 21-16,17-21, 21-15.

The reigning women's singles Olympic champion and world No 1 An Se-young, however, proved too strong for China's world No 2 Wang Zhiyi, who put up a gusty fight, but was outplayed over 57 minutes, and in straight sets, by the mighty An.

An's almost flawless performance, underlined by her finishing the tournament without dropping a game, has seen her rack up 11 victories out of 15 total meetings against Wang.

"Regardless of the result, it was a great learning curve for me," the 25-year-old Wang said of the loss.

"A veteran and champion like her, they always prevail in problem-solving, decision-making and in dealing with the pressure. This is where I think I need to improve as well," she said.

The glimmer of hope for the South Koreans, provided by An, was soon dimmed by China's own veteran, as a rampant men's world No 1 Shi Yuqi restored the host's advantage by routing Jeon Hyeokjin in straight sets in the decisive third rubber.

The attacking game of Shi, who'd won all three previous meetings against Jeon before Sunday, proved too much for the South Korean, as the 29-year-old Chinese star maintained the recent momentum that saw him win his second career All England Open title in March.

Once hailed as the successor of the legendary Lin "Super" Dan, Shi suffered a series of setbacks early on in his career, including three surgeries and a disciplinary suspension, which had threatened to ground his career before it fully took flight.

The spell of misfortune, however, has simply proved to merely be a test of character on his path to something great, as his newfound momentum is building at just the right time.

"First of all, Shi Yuqi, because he's in very good condition and he takes better control of his game now than he did," Zhang replied when asked which player had stood out for him throughout the tournament.

Although twice failing to go beyond the quarterfinals at the Olympics, Shi, who was stopped by Danish two-time Olympic champion Viktor Axelsen and Thailand's Kunlavut Vitidsarn at Tokyo 2020 and Paris 2024, respectively, remains steadfast in his ambition to break through on the ultimate stage.

"I appreciate the team's trust in me, because I was not at my best before this championship," said Shi, who was banned for 10 months by the CBA due to his "unsportsmanlike" behavior when he chose to retire abruptly from his 2020 Thomas Cup semifinal match against Japan's Kento Momota.

"Hopefully, I can use my takeaways from this week in Xiamen to better prepare for future tournaments," he said.

With the Xiamen crowd on their feet, roaring their side on, China's world No 1 women's pair, and Paris 2024 silver medalists, Liu Shengshu and Tan Ning delivered under pressure, beating Baek Ha-na and Lee So-hee 21-14, 21-17 in 55 minutes to seal the championship for the host.

"Liu and Tan also played well in the women's doubles, showcasing their heavy smashes and strong attack," said Zhang.

Liu, 21, and Tan, 22, are expected to help Team China maintain its tight grip on women's doubles at major international tournaments leading up to the Los Angeles Games in 2028.
