How many players so far have won World Junior Title and eventually won the World Championships? for raughly looks, I found that MS: Sun Jun WJC: 1992 WC: 1999 Chen Jin WJC: 2002, 2004 WC: 2010 WS: Gong Ruina WJC: 1998 WC: 2001 Wang Yihan WJC: 2006 WC: 2011 Wang Lin WJC: 2007 WC: 2010 Ratchanok Inthanon WJC 2009,2010,2011 WC: 2013 for WD, MD, and XD, there are players that won both WJC and WC, but mostly they change their partners, If anyone could list the name, it would be nice. Note1: WJC starts at 1992, so some players didn't have a chance to play in WJC (and I believe if they play, they may win WJC too, such as Susi Susanti) Note2: many World Champions rule the world without WJC such as Super Lin Dan right now
