After capturing Chinese national titles in the 100, 200, 400 and 800 free over the course of the week, Sun Yang won his fifth on the final day when he took the men’s 1500 free to close out the meet in Quindao.
Sun won the mile in 15:04.10, improving to tenth in the world. He was the World Champion in the event in 2011 and 2013 and set a world record on his way to Olympic gold in 2012, but he did not show up for the 2015 World Championship final and finished outside the top eight at the 2016 Olympics in Rio.
Ji Xinjie took second behind Sun in 15:07.79, just edging out Qiu Ziao (15:07.81).
Xu Jiayu also completed a sweep, winning his third men’s backstroke national title in four tries. His finals time of 24.48 was just a touch slower than his semifinal time of 24.42, which ranks first in the world this year. Li Guangyang finished more than a second back, but his time of 25.50 was good enough for second, and Zhou Yibing was third (25.74).
After setting a national record in winning the 200 IM days earlier, Wang Shun finished again atop the field in the men’s 400 IM, stopping the clock in 4:12.65 to claim the No. 6 spot in the world rankings.

Liu Zhang broke into the world top ten when she won the women’s 50 free in 24.81. Zhu Menghui touched second in 24.90, claiming the 12th spot in the world rankings, and Wu Qingfeng finished third in 25.08.
