Ding Junhui's remarkable 9-5 victory over Stephen Hendry in the 2005 China Open final spearked the snooker boom that has enabled the game to expand into China.
Ding turned 18 that week and a star was born. Very quickly he won two more ranking titles before his demoralising defeat to Ronnie O'Sullivan in the 2007 Masters final and the general level of expectation on his young shoulders caused him to take two steps back.
He turns 24 tomorrow and will play Hendry again later today for a place in the Beijing quarter-finals.
Hendry is not the player he was then but produced a first rate display to whitewash Matthew Stevens on Monday and, battling for his top 16 place, remains dangerous.
Ding should probably have lost to Kurt Maflin but it's often the case that players who survive a first round scare grow stronger as they make the most of their reprieve.
Judd Trump reached the semi-finals of the 2008 Grand Prix but has done little of note since on TV. He admitted yesterday that this had got under his skin but, at 21, there is obviously time to turn things round.
He will need his wits about him, though, against Mark Davis, a highly experienced player full of confidence who played very solidly to see off Stephen Maguire.
Neil Robertson has, surprisingly, never been to a quarter-final in China and has lost to Peter Ebdon there twice in the last year.
Ebdon, who won this title two years ago, remains reliably tough, although inconsistent. One thing that has always played on his mind is the playing conditions and they have been superb this week.
Ricky Walden has beaten John Higgins twice but both victories came over six years ago and Higgins, though not at his very best, competed well against Nigel Bond yesterday.
Mark Selby got sucked into yet another grind against Tian Pengfei but ultimately came through and should find his contest with Robert Milkins to be more free flowing.
Ryan Day beat Ronnie O'Sullivan for the second tournament running. O'Sullivan played as if it were an exhibition - he even wore his exhibition shirt - and looked thoroughly bored and dispirited in the press conference afterwards.
Maybe the Crucible will inspire him but he is clearly out of love with snooker, or at least proper competition snooker, right now.
Day faces Stephen Lee, him of the miracle 5-4 win over Mark Williams earlier in the week.
Wildcard Li Hang has already beaten two world champions - Ken Doherty and Graeme Dott - and now faces another, Shaun Murphy, who, like the other two, is on a hiding to nothing.
