Alexander Levy moved into second position at the Shenzhen International after finishing his delayed third round.
Lee Soo-min still leads the way by three strokes heading into round four of the European Tour tournament following his 70, but will have to be weary of Callum Shinkwin, who carded a remarkable 10 under to move into second alongside Levy and Lee Slattery.
The third round was heavily delayed due to inclement weather on Saturday, leaving contenders Levy, Paul Dunne, and Joost Luiten to finish their rounds on Sunday.
Levy shot a 66 to move within three shots of Lee after a flawless back nine in which he carded birdies on holes 12, 14, 16 and 18.
Luiten could only par to finish his delayed round, slipping four places down the leaderboard, while Dunne ended the round one under, to sit eight under through 54 holes and tied for ninth.
Earlier, Shinkwin was the big mover as he played a flawless round.
The Englishman moved up 35 places up the standings, posting three birdies on the front nine before backing it up with five birdies and an eagle on the back nine in a remarkable display.
Lee held onto his lead with a strong performance, despite a 17th-hole bogey.
Bradley Dredge shot four under to move up into fifth, but is still four shots off the pace.
