On July 28, the 2025 World Aquatics Championships in Singapore entered its third day of diving events, featuring the men's 3m synchronized springboard and the women's 10m synchronized platform finals. Team China secured two gold medals in these events, with Wang Zongyuan/Zheng Jiuyuan and Chen Yuxi/Zhang Minjie taking the top spots, respectively. In swimming, which entered its second day, Qin Haiyang claimed the first gold for China in the swimming category by winning the men's 100m breaststroke final with a time of 58.23 seconds.

Qin Haiyang had advanced to the final with the fastest time in the semifinals, clocking 58.24 seconds. In the final, swimming in lane 4, he trailed Italian swimmer Nicolò Martinenghi at the 50-meter turn, but surged in the second half to overtake him and finish in 58.23 seconds.

 Martinenghi took silver in 58.58 seconds, while Kyrgyz swimmer Petrashov earned bronze with 58.88 seconds. After the race, Qin remarked, “It’s been a tough period for me, and now I finally feel like I’m back on track. It hasn’t been easy.”

In other swimming finals, Zhang Yufei finished fourth in the women’s 100m butterfly with a time of 56.47 seconds. In the women’s 200m individual medley final, 12-year-old Yu Zidi placed fourth with a personal best of 2:09.21, just 0.06 seconds away from a podium finish.

In diving, the Chinese pair Wang Zongyuan/Zheng Jiuyuan won the men's synchronized 3m springboard title with a score of 467.31. It was their first time competing together in this event at a World Championships. The Mexican pair took silver with 449.28 points, while the British team claimed bronze with 405.33. “We were both very nervous and felt a lot of pressure,” Wang Zongyuan admitted after the competition. “But overall, from the prelims to the finals, we performed well and got better with each round.”

In the women's synchronized 10m platform final, Chen Yuxi and Zhang Minjie captured gold with a score of 349.26, nearly 45 points ahead of the runners-up. This was China’s fifth gold medal in diving at the current championships. The Mexican duo Gabriela Agúndez García and Alejandra Orozco won silver, while North Korea’s Jo Jin Mi and Kim Mi Hwa claimed bronze.

Although it was also the first time Chen Yuxi and Zhang Minjie competed together at the World Championships, they showed great coordination and led the competition from start to finish. In their second dive (301B), some judges awarded a perfect score of 10. Their fourth dive (407C), with a difficulty of 3.2, earned them the highest single-dive score of the competition—87.36 points.
