The weather once again wreaked havoc at the Shenzhen International as thunderstorms forced the completion of round four to be suspended until Monday with Lee Slattery, Soomin Lee and Alexander Levy in a three-way share of the lead.
Delays of over six-and-a-half hours on days one and two meant that every round ran over to the following day, and further storms on Sunday meant it was impossible for round four to finish on time.
It appeared as though Lee - who had seven holes of his third round to finish in the morning - would take a commanding lead as he led by five shots on the 17th tee.
However, a double bogey on the 17th and three dropped shots in the first eight holes of his final round saw his advantage diminish.
The South Korean recovered the situation with birdies at the 10th and 13th holes, though, and is still well in contention to take the title in China on 14 under with five holes remaining.
Levy made his move with three birdies in five holes to complete a six-under-par 66 in round three, and started his final 18 holes by going two under through 12.
Slattery also had to complete round three and returned to the course at 6.30am local time, a birdie at the last seeing him three shots behind Lee after 54 holes.
The Englishman was two under for his final round through 13 holes before the darkness descended to halt his progress, as he bids for a third European Tour victory.
Scott Hend, who made a brilliant albatross on Saturday, mounted a fantastic charge as a score of 66 left him one shot adrift, but he has now completed all four rounds.
Joost Luiten and Brandon Stone are also one stroke back, the former has three holes left while the latter will play five more holes.
Two-time Masters champion Bubba Watson also surged up the leaderboard with a final-round 66 to complete his tournament at 10 under.
