"200m is not my favorite event but I expected to swim faster. However, I found out that my turns were terrible. I need to work on that in the future training. I felt tired after 1,500m and 4X200m freestyle relay and I tried my best, " said Li, who finished second in 1,500m behind teammate Wang Jianjiahe and anchored in the winning relay team.

Zhang Yufei of China ruled women's 200m butterfly in 2:06.51, followed by Mochida Sachi and Hasegawa Suzuka, both of Japan, in 2:08.72 and 2:08.80, respectively.

"I dreamed to win this title but I was too nervous. My coach told me to swim as brave as I can in the first 100 meters. I did it!" said the 20-year-old who collected a silver in 100m butterfly.

Zhang later joined the squad together with world backstroke champion Xu Jiayu, breaststroke swimmer Yan Zibei and women freestyler Zhu Menghui in the mixed medley relay.
