according to a chinabadminton report, Chen/Jiang retired from the WD semi-final match to Huang/Gao on purpose. that is to give Huang/Gao more rest to battle their potential opponent Ra/Lee. this is the similar situation as the Olympics. as Ye gave up her place to Gong so Gong can fight Camilla. however, this time Zhang/Wei managed to beat the Korean pair. i have only read one report of this, i also wonder if this is just a rumor generated by the reporter/media.
