I m so anticipate to watch world championship this year . If in-form Chen Yufei and Huang Dongping can win gold medal , they will be the fastest in badminton history to complete grand slam in a year . Olympic , World Championship , Uber Cup , Sudirman Cup . Anyway , what the 5 stars at the back of the chinese team shirt mean ? - Olympic - Sudirman Cup - Thomas/Uber Cup - World Championship - and asian game ?
