On the penultimate day of Chinese nationals in Shaoxing, East China, Olympic silver winner Jiao Liuyang completed a butterfly triple by adding the 50m crown to those she won over 100m and 200m. Jiao, from the Guangzhou Army team, clocked 26.04sec, 0.04sec inside her own national mark, set in the semis on Friday. 

That Friday session saw one Asian record and two national records fall, the regional standard going to Jiao in 57.16sec over 100m butterfly, 0.22 seconds faster than the previous mark held by Zhou Yafei.

Jiao, 18, told local reporters: "After the Beijing Olympic Games, I started to strengthen the sprint training and that's why I swam to my personal best over the 50m and 100m, while my 200m was yet to reach my peak form."  After winning the 50m, Jiao said that her sprint work was geared to improving her "favourite" event - 200m

In the 50m, Zhou Yafei, described by Xinhua agency as Jiao's teammate and a member of a different army - the Chinese Army - team, and Hong Wenwen, of Hubei, clocked 26.12 and 26.43 respectively.
