Qiu Bo and Chen Aisen completed a week of Chinese domination by claiming 10 metres platform gold and silver medals at the International Swimming Federation (FINA) Diving World Cup in Rio de Janeiro, an event widely hailed as a success.
Bo, a three-time individual world champion who claimed an Olympic silver medal at London 2012, produced a series of superb dives in the Maria Lenk Aquatic Center to win with 557.75 points.
Compatriot Chen, a 10m synchronised gold medal at last year's World Championships, claimed the silver medal in 534.25.
“Diving is a sport in which your main opponent is yourself, so I and Aisen are part of a team and we don’t hide nothing from each other," said the winner.
"We only train a lot and always look to improve.
"Today the semi-final was very close to the final.
"I felt a little bit tired and I noticed that I did some mistakes, but I like my result very much."
A distant bronze medal went to United States' David Dinsmore with 497.05 points.
The performance earned America a second quota place at Rio 2016.
His team-mate Steele Johnson finished fourth with 481.40 points.
The World Cup doubled as a Rio 2016 test event as well as a qualifier, with 88 spots attributed across all eight events.
“The athletes were satisfied and this is the most important to us," said FINA executive director Cornel Marculescu.
"Test events are made for this, to test structure, organisation and services.
"Everyone dived and tried an outdoor arena and the climatic conditions.
"The Maria Lenk Aquatic Center is a great arena, just needs some adjustments.
"The issue of electricity is now completely solved.
"Making a comparison with the notes of diving I would give 8.5 to the event.”
