Soomin Lee earned a two-shot victory at the Shenzhen International after bad weather forced the tournament into a fifth day.
The South Korean shared the lead with Lee Slattery and Alexander Levy when play was suspended on Sunday due to heavy rain and electrical storms.
On Monday morning, Soomin pulled away from his challengers by shooting a birdie on the 16th hole and an eagle on the 17th.
Slattery and Levy fell to tied-fourth by the end of the round, while Joost Luiten and Brandon Stone finished joint-second, two shots off the top on 14-under-par.
