The world No 4 pair went down to current All England champions Guo Xin Wa-Chen Fang Hui 19-21, 15-21 in a 42-minute match.

The Malaysians made many unforced errors, in a far cry from their determined play in the last two rounds.

The world No 9 Chinese pair will meet either compatriots Feng Yan Zhe-Huang Dong Ping or Rehan Naufal Kusharjanto-Gloria Emanuelle Widjaja from Indonesia in the semi-finals tomorrow.

It was a disappointment for Tang Jie-Ee Wei, who reached the semi-final stage of last week’s Japan Open before losing, also to a Chinese pair.

Tang Jie-Ee Wei are still in the hunt for their first title this year. Their last title was won at the Korea Open last year.

As quarter-finalists, they have won US$12,500 (RM52,700).

The tournament offers total prize money of US$2 million (RM8.4 million), with winners in the doubles events taking home US$148,000 (RM624,000) and the runners-up US$70,000 (RM295,146).

Losing semi-finalists will get US$28,000 (RM118,000).
