China is using its home advantage to full effect at the world championships, winning its second gold medal in diving on Sunday.
Qiu Bo and Huo Liang dominated the men's 10-metre synchronized event, earning eight perfect 10s while totalling 480.03 points during the six-dive final.
It was Huo's third consecutive victory in the event at the worlds, having teamed with a different partner to win two years ago in Rome and in 2007 at Melbourne.
"I am happy to win the title because we work very hard," said Huo, the 2008 Olympic champion in the event with Lin Yue, who is injured.
Germany's Patrick Hausding and Sascha Klein earned the silver with 443.01.
Oleksandr Gorshkovozov and Oleksandr Bondar of Ukraine took the bronze with 435.36. They earned the only other 10 of the competition for their inward 3 1/2 somersault.
Eric Sehn of Edmonton and Kevin Geyson of Winnipeg raised their Olympic participation hopes by placing eighth with a score of 386.70.
The pair needed a top-three finish to earn an early Olympic qualifying spot for Canada. Their next opportunity will be in February at the FINA World Cup where they will need a top-eight finish.
"We're really excited by our performance today," Sehn said. "It really puts it in perspective that it is possible for us to get that Olympic spot especially when you consider we did miss a dive in the final. We concentrated really well and our diving was strong overall."
The pair have only been together since last year's Commonwealth Games.
"We are progressing really fast," Geyson added. "It's an amazing result today considering we've been together for less than a year and other teams have been together for many years. This was my first worlds and I was really happy we kept it together and picked it up in the final."
The preliminaries on women's one-metre springboard, a non-Olympic event, were also on Sunday's program. Jennifer Abel of Laval, Que., was 14th and did not advance.
China won the first gold medal awarded at the championships on Saturday, when Wu Minxia and He Zi claimed the women's 3-metre synchro event.
China's golden haul could continue on Monday and Tuesday because the country has the leading qualifiers for the men's and women's 1-metre springboard finals.
"They are like the table tennis players, they don't make any mistakes," International Olympic Committee president Jacques Rogge told The Associated Press about the Chinese.
Rogge attended the event with FINA president Julio Maglione on a humid night at the outdoor pool, and Rogge helped present some of the medals.
Qiu and Huo, who is from Shanghai, had the partisan fans cheering loudly on their second dive, a reverse that earned them five 10s — three for execution and two for synchronization.
They added another 10 on their next dive, then finished off the performance with two 10s on a backward 2 1/2 somersault with 2 1/2 twists.
Americans David Boudia and Nick McCrory finished fifth, two years after Boudia won the silver with a different partner in Rome. They were third after three rounds before creating a big splash on their most difficult dive.
Then on their fifth dive, McCrory's legs smacked the water upon entry, earning the duo's lowest marks of the competition.
Peter Waterfield and Tom Daley, the 10-metre champions in Rome, finished sixth, but Britain is assured of a spot in the synchronized events as the host nation at next year's London Olympics.
The 17-year-old Daley's training has been affected by the death of his father in late May, while Waterfield arrived for the meet from the team's training camp in Xian with flu-like symptoms.
