Mixed doubles pair Chris Adcock and Gabby White bowed out at the first-round stage of the All England Open after defeat by top seeds Xu Chen and Ma Jin of China.
The English duo did not recover after falling 9-2 behind in the first game going on to lose 21-14 21-18.
"They're the best in the world and they showed that - but we learnt a lot," said White, who is Adcock's fiancee.
Scotland's Robert Blair was the only British player to taste victory.
He and Malaysian partner Tan Bin Shen beat Indonesia's Alvent Yulianto Chandra and Markis Kido 17-21 21-19 21-15 in the men's doubles.
"I am very happy," said Blair. "We haven't played too much together, so to perform like that against a pair like that is very nice. It is good to come through a close match."
Adcock's men's doubles campaign with Andy Ellis ended in the first round.
The pair, ranked 23 in the world, were edged out 21-29 24-22 in a close match against Malaysian pair Koo Kien Keat and Tan Boon Heong at Birmingham's National Indoor Arena.
Adcock had high hopes before the match, especially after he and Ellis had beaten world number one duo Mathias Boe and Carsten Mogensen a fortnight ago.
"I thought we had the game to beat those two," said Adcock, after defeat by the second seeds. "We put ourselves in winning positions, especially in the second, and let it slip, which was very disappointing."
White was also beaten in the women's doubles, playing alongside 21-year-old Lauren Smith in a 21-16 21-7 defeat by Ma and Tang Jinhua,
Adcock's former mixed partner Imogen Bankier went out of the women's doubles with Bulgaria's Petya Nedelcheva against seventh seeds Jung Kyung-eon and Kim Ha-na.
Men's singles top seed and two-time champion Lee Chong Wei recovered from match point down to beat Hong Kong's Wong Wing Ki 13-21 21-6 23-21.
Women's singles top seed and Olympic champion Li Xuerui of China lost to South Korea's Bae Yeon-Ju. Compatriot and third seed Wang Yihan also went out.
