Chinese swimmer Wang Qun made her 14th birthday memorable, winning gold in the women's 100-meters breaststroke over Olympic champion Luo Xuejuan at the East Asian Games in Macau yesterday.
Chinese swimmers grabbed seven out of eight golds available yesterday.
In athletics, China won five out of eight gold medals on the final day of that part of the competition.
Wang, who joined the national swimming team after winning the Chinese high school games in September, beat her more heralded teammate at the 50m mark and pulled further away to finish in 1:08.56, 0.58 clear  of Luo and a further 2.20 seconds ahead of Japan's Sayaka Nakamura.
"Wang Qun has made quick progress and she is very promising," Luo said.
"I was very disappointed with my result," added Luo, who triumphed over 100m in 1:06.86 at last month's China National Games.
"I had a cold and a stomachache. But that can't be used an excuse for such a mediocre time," she said.
Wang's win was followed by Yang Jianqiao's 16:24.10 winning time in the women's 1,500m and China's triumph over Japan in the men's  4x100m freestyle relay.
Yang's gold was China's 100th in Macau.
China also reached the lofty total when Shanghai hosted  the inaugural East Asian Games in 1993.
Earlier, Pang Jiaying won the women's 200m freestyle in 1:58.49, Ouyang Kunpeng shattered his own Asian mark by clocking 25.18 to  win the 50m backstroke, Zhou Yafei set a new games  record of 58.43 to take the women's 100m butterfly, and Wu Peng won the men's 400m medley in 4:20.50.
Japan's Daisuke Kimura ruined an otherwise perfect night for China as the 24-year-old out-touched China's Xue Ruipeng in the men's 200m breaststroke.
In athletics, Xing Huina, one of 11 Chinese Olympic champions in Macau, put up an erratic run under a hot sun as she claimed the women's 5,000m in 16:04.56 in Macau Stadium.
The time was way outside of the 15:20.09 that won her the China National Games title in Nanjing last month.
The 21-year-old, who also won the 10,000m in Nanjing, exchanged leads with Japan's Hiromi Ominami six times until she surged ahead 300m from the finish line.
Ominami finished second in 16:10.77, nearly 25 seconds ahead of South Korea's Bae Hae-jin.
Xing said the hot weather combined with fatigue from the national games had taken a toll.
"It's too hot and this result didn't show my true strength," she said.
China won 26 gold medals from 45 track and field events while Japan collected 16 golds.
The remaining three went to South Korea.
China opened the day by winning the women's 100m hurdles courtesy of Feng Kun. She finished in 13.09 seconds.
Zhang Qi set a new record  in the men's shot put. His toss of 20.06m gives him the East Asian Games record.
Wang Hailan lifted China's fifth gold of the day after amassing 5,932 points in the heptathlon.
China's foursome clocked 3:33.59 to win the women's 4x400m relay.
Japan grabbed the last athletics gold in the men's 4x400 relay, which China did not enter.
Earlier, Japan's Yuki  Nakamura added a men's 5,000m gold to the 10,000m title he won three days ago.
South Korea's Kim Deok-hyeon rounded out the track and field competition with a 16.79m win in the men's triple jump.
Chinese Taipei grabbed two  tennis golds, making it four out of five on the court.
Chinese Taipei pair Chan Yung-jan and Chuang Chia-jung defeated Japan's Mayumi Yamamoto and Tomoko Yonemura 6-0, 7-5 in the women's doubles final.
