Goodbye Badminton World Federation, goodbye my beloved badminton. You have heartlessly shattered our dreams,” Yu wrote on Weibo, a social network site.DisqualifiedThe controversy also saw the BWF disqualify two South Korean pairs and one Indonesian team after they responded to Yu and Wang’s antics by also attempting to lose.Their places in the draw were taken by pairs from Russia, Canada, Australia and South Africa, with the Russians set to play top-seeded Chinese duo Tian Qing and Zhao Yunlei, who the disqualified teams were trying to avoid, in the semi-finals.
