Golf Johnnie Walker ClassicAdam Scott played eight holes while Michael Campbell, Retief Goosen and Peter Hanson completed 36, but they all share the lead after a confusing second day of the Johnnie Walker Classic in Beijing.
Scott finished birdie-eagle-birdie to card a course-record 63 in the delayed first round, and then spent the afternoon visiting the Great Wall of China.
In stark contrast, those - such as Peter Lawrie - who had not struck a ball in anger at Pine Valley on Thursday, when high winds disrupted play, then tried to play two rounds in one day as the €1.83 million event attempted to make up for lost time.
Only 42 managed to play all 36 holes, but among them were Campbell, Goosen and Hanson, who all joined Scott at the top of the leaderboard on nine under par.
Campbell and Hanson, the winner of last week's Spanish Open, recorded superb second rounds of 65, while Goosen added a 67 to his opening 68 for a halfway total of 135.
Lawrie also completed his second round, a one-under-par 71 that included six birdies but three bogeys and a double bogey, and was lying in tied 11th spot on four under par.
Colin Montgomerie had threatened to join the leaders after an opening 68 and four more birdies in his second round, but two late bogeys left the former European number one with a 70 and three off the pace on six under.
Campbell, who missed the cut in his first five events this season, is starting to reap the rewards of employing his coach, Jonathan Yarwood, full-time.
"There were a few occasions last year when he came over to see me because he works for the David Leadbetter Academy and they wouldn't release him," revealed Campbell, who was 12th on his last appearance in China last month.
"It was pretty frustrating, so we decided to do something about it and employ him full-time. It's been hard work the last six months or so, but I took four weeks off after China and worked hard on my game and came out all guns blazing.
"I shot the worst 70 in the world in the first round - I was making bogeys from 90 yards out - but I knew my game was good enough to shoot a low one and the second round was quite an easy 65.
"I'm fit enough to play 36 holes and we were fortunate to play 36 in these good conditions. After the pro-am on Wednesday and Thursday's wind I thought three over par could win this tournament.
"If Adam doesn't go crazy tomorrow then we have a chance, and the weather forecast is pretty horrendous."
Indeed, torrential rain and lightning are forecast.
Ernie Els was eight shots off the pace despite playing the last eight holes of his first round in three under.
