"Shi is a newcomer. We pair with each other because we have a similar rhythm. We train so hard and know each other better and better since we started training together for the synchro event. We hope we can be more synchronised in the future," Wu said.
Olympic champions Chong He and Kai Qin also partnered for the first time and took out the men's 3m springboard synchro with a total 468.90 points. The new pair met little challenge in the final as they pulled away the six other pairs competing after the first round and never looked back.
"This is our first international event as a pair, I'm happy to train together with Qin, who is my best friend," He said.
"Today's result is better than what we expected because we only trained with each other for one month."
Russians Evgeny Kuznetsov/Ilya Zakharov finished second with a margin of 38.58 behind the Chinese while Mexico's Yahel Castillo/Daniel Islas placed third with 396.15 points.
