Zhang Yufei snatched two gold medals on Wednesday at the Chinese National Swimming Championships in Qingdao, east China's Shandong Province, as she stormed to win the 200 meters butterfly and anchored in the winning quartet in 4x200 meters freestyle relay. 

Zhang, who clocked 2:06.11 and 2:06.31 in heats and semifinals, dominated the final in 2:05.44, the fastest time on the world rankings since 2019. 

"I really want to break the barrier of 2:05.00, but I missed the cut since I have competed in 100 meters butterfly, 100 meters and 200 meters freestyle so far, I feel exhausted," said the 23-year-old, who tied her own national record in 100 meters freestyle with 52.90 on Tuesday evening heats. 

Later, Zhang joined the mixed team in the 4x200 meters freestyle relay and won the race in 7:59.45, beating teams from Hebei and Shandong into second and third. 

In the other three men's finals, 100 meters champion Yan Zibei claimed victory in 200 meters breaststroke in 2:10.80, Cheng Long topped the 800 meters freestyle with 7:58.63, and He Junyi took a narrow victory in 100 meters freestyle with 48.71, 0.03 faster than runner-up Pan Zhanle. 

The nine-day championships, which serves as one of the trial events for the Tokyo Olympic Games, has attracted more than 500 swimmers from 26 teams.
