BEIJING - Returning to the pool after a five-month break due to injury, the Chinese synchronized swimming duo of Jiang Wenwen and Jiang Tingting found out it is no longer the peerless team of the pool at the 2011 China Synchronized Swimming Open in Beijing, which was held from April 22-25.

The twin sisters, once regarded as China's first and only choice to compete at international events, were forced to skip the national team's winter training due to an accumulation of injuries.

At their first appearance after the Guangzhou Asiad, they were overshadowed by national teammates Liu Ou, Huang Xuechen in duet tech, and suffered another close loss to Liu and Luo Qian in duet free.
