    The Chinese paddlers had already sealed the trophy by wrapping the top four seats after the quarterfinals on Saturday.

    Ma Long, newly-crowned world's No.1 player, fought from behind to overcome same-aged Zhang Jike in six sets (3-11, 10-12, 11-6, 11-5, 11-3, 11-8).

    "I did not put myself into the match as early as he did," said Ma, who lost the opening set in 3-11 and missed the second by just two points. "However, I am glad that I concentrated a hundred percent afterwards and did well in the last four sets."

    Xu Xin, on the other hand, survived a tough battle between two classic attackers also in six sets (11-8, 6-11, 13-11, 7-11, 14-12,11-9).

    Xu, who just celebrated his 20th birthday, held back three set points from veteran Wang Liqin in the fifth set to take over in 14-12, which became a decisive point of the whole match.

    "The three set points, which I missed in the fifth set, turned out to be fatal," said Wang.

    The former No. 1 player in the world, now 31 years old, denied a possibility of retirement despite a two-year title draught.

    "I am carrying on with my career without any backup plans," said the world champion in 2007. "I will try my best to vie for a ticket to London Olympics until the last minute."

    Xu, now ranked 15th in the world's list, made a name here by stepping over Germany's top paddler Timo Boll in the first round before easing past another German Bastian Steger to reach the semifinal.

    "I am young and I have little pressure, which I think brought me here to the final," he said.
