Chinese won two events of the field competitions -- women's shot put and javelin throw -- at the IAAF Diamond League Shanghai on Sunday.
Inspired Gong Lijiao fired off two world leading puts to give China a spectacular winning start to the evening as the world and Olympic bronze medallist beat Christina Schwanitz on home soil.
Gong opened with 19.82m, and immediately responded to her German opponent's second round effort of 19.94m with 20.23m.
Gong produced three other efforts over 19m to take her first Shanghai Diamond League win since 2011. Another Chinese Guo Tianqian made it a brilliant opening competition for the hosts as the 19-year-old world junior champion improved her own personal best by 20cm to take fourth with 18.57m, just 9cm behind third-placed Tia Brooks, Moscow world championships finalist from the United States.
"I'm very satisfied with my performance today. I will try my best to change the color of my medal this summer in Beijing since I have got bronze twice before," said Gong. "The atmosphere of the stadium is very good and I like Shanghai."
In women's javeline throw, China's Lu Huihui notched 64.08m in her third attempt to add the second gold for the host. South African Sunette Viljoen finished second in 63.30m. Australia's Kimberley Mickle was third.
In men's high jump, Mutaz Essa Barshim of Qatar cleared a meet record of 2.38m to beat Ukraine's Bohdan Bondarenko's 2.32. China's Zhang Guowei took third place due to count-back.
Nigeria's Blessing Okagbare showed Jamaica's world-beating sprinters a clean pair of heels as she blasted clear of the women's 100m field to win by more than a 10th of a second from USA's Tori Bowie in 10.98.
After her double victory here last year, the Nigerian again had the Shanghai crowd gasping in appreciation as she pulled away from the fast-starting Veronica Campbell-Brown in the second half of the race, towing Bowie to her best of the year, 11.07.
Campbell-Brown faded to fourth behind Michelle-Lee Ahye of Trinidad and Tobago who clocked 11.13 while double Olympic champion Shelly-Ann Fraser-Pryce was never in it. The triple world champion finished fifth three hundredths behind Campbell-Brown in 11.25.
A thrusting finish from Alonso Edward was just enough for the former world silver medallist to beat three fancied Jamaicans in the men's half-lap (200m) race that failed to catch fire.
The Panama sprinter stuck his chest across the line to clinch the four Diamond Race points in 20.33, just three hundredths faster than Julian Forte. Nickel Ashmeade, the man he beat by a point to claim the 2014 Diamond Race, was third in 20.44 with a third Jamaican Rasheed Dwyer fourth.
After wins by Usain Bolt and Warren Weir, Edward is the first non-Jamacian to win the 200m here since USA's Wallace Spearmon in 2009.
In men's 110m hurdles, American David Oliver edged out Orlando Ortega to win the Shanghai meeting's showcase event in 13.17, his fastest time of 2015.
The world champion was out hard and held on to beat the fast-finishing Cuban by two hundredths of a second with world record holder Aries Merritt third in 13.25.
Last year's winner Xie Wenjun couldn't repeat his 2014 heroics and give the crowd the rousing climax they hoped for. With the celebration of Liu Xiang's career retirement next up on the agenda, Xie had to settle for sixth in 13.36.
In men's 400m, a commanding run from Kirani James of Grenada brought the Olympic champion a comfortable victory over his archrival LaShawn Merritt in 44.66 as Merritt's USA teammate Tony McQuay stole second in 45.54.
In women's 800m, last year's Commonwealth and African champion Eunice Sum of Kenya sealed her first win of 2015 in 2:00.28 to put her on track to defend the Diamond Race trophy she clinched in 2014.
Chased hard by compatriot Janeth Jepkosgei, Sum who won 14 800m races last year strode away from a field of sub-2 minute runners to win by almost half a second.
In men's 1,500m, a controlled kick over the last lap gave Silas Kiplagat of Kenya victory in a world leading time of 3:35.29 as eight men fought for the line down the home striaght.
The Kenyan kicked off his Diamond Race defense by coming from behind to defeat compatriot Hilary Ngetich whose ran a PB of 3:35.40 in second with Collins Cheboi third.
In women's 400m hurdles, a smooth running Kaliese Spencer picked up where she left off in 2014 with yet another Diamond League one-lap hurdles win, the Jamaican beating half a dozen Americans with a world leading time of 54.71.
Tiffany Williams, the world and Olympic finalist, was a comfortable second in 55.27 followed by Cassandra Tate in 55.68.
In men's discus, a last round effort of 64.65m gave Piotr Malachowski an unlikely looking win over fellow Pole Robert Urbanek after the European bronze medallist had taken the lead by 4cm in round two with his season's best of 64.47m.
India's Asian and Commonwealth Games champion Vikas Gowda was third with 63.90 while Estonia's former world and Olympic champion Gerd Kanter did not make the cut.
In men's 3,000m steeplechase, a bold piece of front-running from Jairus Birech brought the defending Diamond Race champion an impressive victory over a raft of fellow Kenyans in a world leading time of 8:05.36.
