Despite an ankle problem, Lee Chong Wei produced one of his finest performances to regain the All-England Open title by beating Chen Long from China in an impressively emphatic straight games win in Birmingham on Sunday.
The world number one from Malaysia beat the titleholder from China 21-13, 21-18 – revenge for his loss to Chen in the final last year.
The variety of the 31-year-old's game was often mesmerising, and his focus was steely enough to resist determined second-game fight-backs by Chen from 4-10 to 9-10 and from 13-18 to 17-18 and to within the width of the net tape of getting to 18-all.
Earlier China won the women's singles when Wang Shixian, the fourth-seeded former All-England champion, beat Li Xuerui, the top-seeded Olympic champion, 21-19, 21-18.
Yu Yang's improbable rehabilitation continued in dramatic fashion also on Sunday as she and her women's doubles partner Wang Xiaoli saved a match point to complete a successful defence of their All-England Open title.
Yu, who had said she was quitting after she and Wang were among those banned during the match-fixing scandal at the London Olympics, was again a bundle of renovated self-belief and forecourt energy as the top-seeded pair edged out their unseeded compatriots Ma Jin and Tang Yuanting 21-17, 18-21, 23-21.
"We really wanted to win again this year," said Wang. "We were quite scared about coming here because we were getting challenged by all the other players, but we managed to adjust and it was really just about playing to the right level."
Indonesia regained the men's doubles title after an interval of more than a decade when top-seeded Mohammad Ahsan and Hendra Setiawan followed their August capture of the world title with a 21-19, 21-19 win over Hiroyuki Endo and Kenichi Hayakawa.
The Japanese pair led 16-15 in the first game and repaired a three-point deficit in the second, and were not far from becoming their country's first All England champions since 1978.
