With a slice advantage of 0.04 seconds, China won the men's 4x100m medley relay, the last final of the six-day swimming competition on Friday, to tie arch-rival Japan 19-19 on the gold medal tally at the 18th Asian Games.
Singapore won the other two golds, while South Korea pocketed another one from the 41-gold bonanza in the pool.
The Chinese quartet, composed of three-time Asian backstroke champion Xu Jiayu, and teammates Yan Zibei, Li Zhuhao and Yu Hexin, beat pre-Games favorite Japan to take the 4x100m medley relay title in a Games record of 3:29.99s. The previous mark of 3:31.37 was also set up by China four years ago in Incheon, South Korea.
Japan was second in 3:30.03 and Kazakhstan came in third with 3:35.62.
"We did our best!" said Xu, who has collected five gold medals from the Asian Games.

"It's not easy for me to win the event for three consecutive Asian Games. I was rusty and exhausted after 4X100m freestyle relay. I even thought of quitting the event, but eventually I did my best as I could," said Sun in tears.
Sun swept all the gold medals from 200m, 400m, 800m and 1,500m freestyles and collected a pair of silvers from the freestyle relays in Jakarta.
