after that loss, i think she has defeated MKY twice already. she has also defeated Wang Yihan in Swiss Open
..it's not so much a matter of beating MKY, twice or thrice or four times after the OG, or WYH or WL or other top shuttlers. That's just part of her process of becoming the current WS WC. Whether or not she beat MKY in this yr's WC, her WC WS title is the redemption for her loss in last yr's OG Bronze medal match.
She is all nothing but a one hit wonder washout now. After her shocking win in Hyderabad, she failed to re-produce the same sort of form subsequently and she has been defeated easily by any players. Going back to 2011 season, she did surprise by making all the way to the final of BAC but that's all that is. She participated in a few tournaments and got herself exited by Saina Nehwal in two back-to-back tournaments. There's goes her prospects, she could only settle down and work as sparring partner for her Wang compatriots instead.
