Qin, two-time champion of 2005 and 2007 worlds, settled for the silver in 530.80, while Aleksandr Dobroskok of Russia coming third in 478.40.

The 21-year-old Qin said: "I'm more focused on the synchro than the individual event in daily training. So I lacked confidence and power compared with Zhang."

In the women's 3m springboard, He Zi claimed her second title; however, she gave herself only 75 points percent satisfaction with her dives.

He, who took the synchronised victory on Feb. 13, met no challenges in the final and finished 386.55 points, 30.15 points ahead of fellow Wang Han in 356.40.

Jimie Elizabeth of Malaysia won the bronze in 286.50.

The 19-year-old He said: "Today's victory is just a reward of my hard work for the last two months. But I think I can dive better. I gave myself 75 points if 100 is the best."

He, 1m springboard winner at the 2007 Melbourne World Championships, said she never thought about defending the title or competing for a spot within China's team against four-time Olympic champion Guo Jingjing and veteran Wu Minxia.

He said: "What I care about is to do my best every day. I will take the chance if I earn it."

The three-day Grand Prix in Shenzhen had three golden-double winners with He, Chen Ruolin on the women's platform and Zhang Xinhua on the men's springboard, while the hosts swept all the eight gold medals of the competition which started on February 13.

The next leg of the Grand Prix will come to Rostock, Germany from February 27 to March 1.
